Same problem. Can't get them to stop calling but if you have to have your phone on try saving the number to your phone and then you should be able to set the ringer for that number to "no ringer" so when they call it won't ring. Doesn't solve the problem completely but gives you a little peace. Good Luck.
It is the Infinity Group, and since I don't owe anyone money, I figure they are just fishing for something or it is for the person who had this phone before me. I wish they would quit calling, just a hassleE9X3
Look Up the Federal Law, that states, once told not to call they must, "cease and desist" calling you, or violate federal law. Also many states have the same law on the books, to stop harassment from collectors.
I get calls from this number...I don't answer. I don't know who's calling, I ain't answering. They can leave a message...which they never do. Schmucks.
