Don't bother to answer.  It will Just annoy you, and likely at an inconvenient moment !

Yes.. "James" has called me several times.. First time from this number, usually from another number. I have opted out every time and still get calls. I have started to file complaints with the FCC and DoNoCall registry.

I've also had "tax relief" calls from "WCA" that I have chosen to opt out, but that apparently only proved I have a working number because the calls keep coming.

This time it was for some sort of rewards program

I just received a call from this number too. Thanks for the info. I will be putting them on my reject call list.

Recording offering some kind of "tax releif" and has a opt out- but gives a random number as being removed.

It has called my cell phone a number of time in the last month.

Received automated voice messages from this number asking if i want to know secrets from the IRS? They've been constantly calling several times per day & it needs to stop.

4 calls from this number and 3 others from 314-627-6883 just today. I have not picked up and the number  314-627-8881 is now sending garbage text which is 16cents/call received.

I keep on getting a call from the above number.  I do not have minutes to pick up the call.  They keep on taking minutes away from my phone.

WCA keeps calling me. I call them back and get a recording that says "WCA Subscriber services, blah, blah, blah."
Don't know how they got my number.
Want to know how to make it stop.

This number has called me. I have no idea who it is!

this caller is from st lewis missouri and is a crank caller

I have friend there and a former client. But it's never them that is calling.
The calls should stop!

Have received several calls over past couple of days. I didn't answer them!

Just called me 4 times IN A ROW.
This needs to stop.
Like now.

Automated messages from "Bill with WCA" are arriving more and more regularly and I would like them to stop.

Where is this from?
