My husband and I are senior citizens. We are receiving at least 5-6 phone calls per day from an 800 number that CLAIMS to be Amazon.com VISA card saying that I owe them $53. I have called Amazon.com and they said that I not only don't OWE them anything, but that they haven't called me and that I have a credit balance. I've asked ~ BEGGED ~ these people to stop calling me because every time they call, either I or my husband have to stop whatever we are doing and answer the phone. Many times we are involved in doing other things and this is a nuisance and a physical difficulty. I don't know who these people are and neither does the legitimate Amazon.com. I had my credit card cancelled and had a new one issued because I feared they had my old card number. The number from which they are calling 5-6x a day is: (800) 945-6596. It is always the same number,but a different person.
