Who called from 7733707921

received 2 separate phone calls from this #. no message.

Dead air. Blocked.

Call starts off with recorded message about eliminating credit card debt and then asks you to HOLD for next available agent to come on line.

Three calls. All ended with no spoken word from caller. I called back after third call. Call was unable to be completed.

Just received a call from this number wanting to lower my interest rate on my credit cards. Asked  for my credit card number. It's a scam
