I have gotten several calls coming from this number and since the calling party is not known to me I let the call ring through to voice mail. No message has ever been left for a return call and after reading the above comments of others this is no doubt some type of scammer.
Called my cell phone offering extended service on a credit card I don't have. I asked repeatedly to be placed on do not call list. Operator didn't speak English and kept rambling ignoring my request.
