My son just got this phone for Christmas and just got this number they have called non stop I tried to tell them This is my son's phone and we just got this number on Christmas eve.. He is only 6 and it's just a little 15 dollar phone he can bring with him to his grandparents..
I work in classroom settings and they constantly call! i talked to them, i informed them that i would be able to make a payment at the end of the month when i am paid, they take a note and say thanks, but will still be called every day.
Make sure they're legit. If you are behind on something, I would call your original creditor, and make sure they sent your past due to a third party.
If they send you something in the mail, send them a Money Order for that amount, but do not give them your banking information. Unfortionatlly I did to another third party, and I'm going to close my checking and savings accounts, and reopen a new one when my final payments are taken.
