calling about an expired car warranty

Some kind of auto warranty deal. Been calling over the last few months.

They call on Sundays?!

Global Crossing stated they have no authority to tell people who to do business with, and pretty much addmitted they are providing service for harrassment and scams and there is 'nothing they can do'. She did tell me both of these numbers are assigned to a company called Omega Services.

As above, this phone number repeatedly calls my Mother's phone number about expired auto warranty.  My 90 year old Mother pressed #1 on the last call and spoke to the male caller briefly.  When she asked him how he got her number, he promptly hung up.  Phone number 978-485-0161 is indicated as Boston residential service provided by Global Crossing.  Global Crossing's Boston office number is 617-648-0400.  I intend to call Global Crossing to complain about their customer's annoying (and perhaps scamming) calls and suggest all of you do the same.

Calling at late hours of the night, waited to get to a person and was disconected. When tried to call them back to take us off the list, the same song was playing over and over. Sat on hold for a long time and no answer of any kind.
Who is the company and why are they calling so much?

This is just one phone number that this company has used to call my home and work phones for the past several months concerning an expired car warranty.  There seems to be no way to get through to them. If I call back, I can leave a message...but I'm pretty sure no one ever listens to the messages.  If I try to get through to an "operator" I get cut off or they hang up when I tell them I want off their list.

No message. Reverse phone said residential phone in  Boston area.

Called while I was out, didn't leave message. Caller ID read "BROOKS PARTNERS."

They keep calling & calling.  Never leave any messages.  All of a sudden getting many calls from unknowns...

Warning that warranty on a car with not much value anymore will expire.

Who are these people and why do they call?
