Conference call Update: Hope this helps
No call yet- I had enough time to call CL&P, local Police, Utility Port Authority, BBB- these are the results:
**CL&P were not aware of Greenwich Cap, but said they aren't always familiar with other suppliers.
**Local Police said nothing they can do unless a crime was committed
**BBB website indicated "Greenwich Cap" was a loan company based out of Tampa FL.
**Utility Port Authority was helpful, they gave me a website www.ctenergyinfo.com - click "choose an Electrical supplier" in the drop down, click "List of Suppliers & Aggregators" - in there you will find ALL the companies, and you can click on them to view and compare their rates and info.

Conference call came in-
** Greenwich Cap called, I mentioned the being unable to locate the business name etc. she told me their company name is Productive Marketing, they are hired by their parent company "Reliable Energy" (found in the Port Authority website list and BBB) to canvas new customers.I spoke to the owner of Productive Marketing (not found in neither BBB nor C.O.N.C.O.R.D), then spoke to the owner of Reliable Energy which confirmed they hired marketers but didnt know all the companies' names, but did confirm he is working with the owner of Productive Marketing, (just didnt know the name of his company).
their phone line is being moved so they are only using an "outbound only" line, which explained the hang ups when I called the number on caller ID. "Greenwich Cap" is their sister company. for whatever it's worth, I hope this helped.

This place calls all the time, can this be stopped?

Hello,
I have made some headway with this issue.  Our name is still showing up as the caller ID, but I have found that the company that really owns the number is called Reliable Power.  I am working with them to fix the caller ID mixup.  I was told that if you do not wish to recieve these calls anymore you can call thier 800 number at 1-800-413-0110 .

Thank You,
Brian

I spoke to the caller from "Greenwich Cap" she said she represents an energy providing company in Wilton (CT) and they can possibly save money by using them as the supplier, instead of CL&P or UI. she indicated that most consumers fall under the Utilities "Default rate" and that by i) verifying your Electric bill info ii) you agreeing to use them, they may be able to save you a lot of money. I told her I didnt have my billing info handy and requested a scheduled call (for today at 10am). Sounds more "probable" than "possible" that its a scam, there must be a way of tracing the call to a location for the authorities.
I tried calling, the automated pick up said "Goodbye" then hung up.
I located the number to Huntington/Shelton CT
She said she's (the company) is in Wilton CT
Caller ID indicated "Greenwich" Cap
Will give an update later, after the call.........

Thank you Brian...still getting calls with Tomra listed as caller as recently as yesterday...I've seen your trucks at grocery stores....hope you get your number back soon!

Receive calls from this number at least 2X per day.  I never pick up.  Finally, I decided to dial the number myself and see what happened.  Reached someone who identified himself as a rep for a group called Reliable Power.  Strangely, when I read back the number I dialed to him he said it's not the group's number and stated that he was calling from a Florida area code, not Connecticut.

Got calls on 2/10, 2/13, 2/14 and didn't answer, they didn't leave a message.  Now another call today, 2/15/12.  I answered - empty line and just as I was about to hang up a male voice said "the candy store is open" and hung up.  DON"T THEY EVER GIVE UP.

No worries Brian, we know its not you.  These days a company would be crazy to use its own name in these telemarketing calls.  Too bad.  They have figured out how to manipulate what shows up on caller id and we all suffer as a result.

Hello,
This is not Tomra calling you.  It is an error somewhere in one of the Big Telco's database.  Tomra does not own that number.  According to this board some people see caller ID of Tomra, some see Greenwich Capital, and some are having an energy provider trying to get them to switch from UI or Connecticut Light and Power.  We have been doing all we can to have our name removed from that number.  We work with Grocery stores and beverage distributors.  We have no reason to call individuals homes.  Sorry for your inconvenience.

Thanks,
Brian

Call several times a day...answered once...no one on other end! Goggled Tomra...they are a recycling company!?

Got a call from this number. ID says Greenwich CAP and they wanted me to sign up for their electric service.

I get a call 1 - 2x per day. Caller id says GREENWICH CAP. I don't pick up, they never leave a message.

I keep getting similar calls, so annoying.  My caller ID says Greenwich Cap?  No idea what that is, when I picked up, nothing.  
Finally decided to use the feature on our ATT Uverse and block the number and a couple of others that are pesky.  Works great, one ring, then, boom, done.
Don't know what kind of phone service you have, but if the feature is available, definately take advantage!

We receive calls on a regular basis (2 or 3 times per day) from "V10310084400000 203-447-8807"
They leave no message, they hang up when we answer and it is getting very annoying. I have tried to call the number 203-447-8807 and I get no answer, just a hang up sound and an annoying busy signal.

The person on the other end asked for my husband. I said it wasn't here. He then asked if I am the person who makes decisions regarding CL&P. I replied, "No, but I...."  But he hung up.

Called this number back and its always busy!  Must be a auto dialer telemarketing call!  I'll just add this number to my list of numbers to be blocked.
