Who called from 7188093295

I received a call from this number and it was a telemarketer.  I told them now and as i was saying to take me off of the call list they hung up on me before i could finish.

said i was in a sweepstakes for Visa and Mastercard holders.

they are calling me every day but when I say hello they don't say anything. and when i call back it says the number is not in service.

is this doogie

Ive been receiving calls from this number on my cell phone, and from another one 216 area code. Not sure how I got on this list but it is aggravating.
