male caller with heavy indian accent called and said he was calling from my credit card company and would like very much to lower my interest rate on my account. I said sure, that sounds great to me, lets do it. He then asked for my account number. I told him I would never give that out over the phone. He insisted that it was necessary so they could verify they were talking to the account owner. I told him he would need to provide more information then to prove he was from my credit card company but before I could finish he hung up.
