Who called from 5802626181

They call multiple times a day and leave no message. When you answer they hang up. If you try to call it back it states it is not a working number.

Once again...I answered when they called. However, they say your name like they are a personal friend then hang up.  I called the number back only to get a recording 'this number is not in service'.

Calls from multiple numbers in last 3 days. All day. 580-262-6181. 641-569-7504. 615-541-1566. All automated. Not sure what list I got on for this to happen.

Something about Ring Central.
