Calls every month or so, but never leaves a message.

left message on ans. machine last chance to get improved rate on my credit card.

They called me 3 times today and every day this week...  I reverse dialed and it said this number is not assigned.   How can I stop these idiots???  they are also calling my mom...

This is another in a series of over 100 calls from this company, sometimes purporting to be Account Services, sometimes an auto warranty company.  I've reported them all to the Do Not Call list which hasn't done any good.

Called this morning - same taped message I've already received dozens of times offering my last chance to improve my credit card rate, but a new number - ID screen showed a cell phone in New Brunswick, Canada - usually it's unknown or FL.
