Who called from 5852070493

I didn't answer and they left no message.  Blocked.

Called twice in three hours, left no message both times.

I answered  the call & no response  from caller & then they disconnected.  I called back & it said at MIDNIGHT they are giving away gift cards , 1 was Walmart. I hung up after that & blocked call

Called me twice. Left no message first time and hung up on me the second time.

Same just happened to me, they called last month too.
