Who called from 3021215622

since there were no reports I called back the number.  It does not ring and then it goes into a fast ring.  Google gives me nothing.

I tried to block the number through my phone company and it said that numbers can't begin with 1 or zero:  that it is an invalid number.  I will just block it on my phone.

Caller said he was calling on behalf of United Healthcare  and said he was a marketeer marketeer. Said a free back brace could be mailed to us. Sounds fishy to me. Can't call back the number⅞4

Call had a heavy accent. I think she was trying tomake final argenments to send my free back brace. I sais i was not interested. Phone was silant, so i hung up. Has scam written all over it.
