It's T-Mobile...they keep calling my number looking for someone else for bill collections.  I asked them to remove the number, but they say that they can't.  Total BS.  I guess I'll be harassed for the remainder of the time that I have my phone number.  UGH!

Call your service provider if it is not TMobile and ask to get the phone number blocked.

Recording of a Darth Vader style voice, identifying himself as "Fausto," says they're calling about a change to you T-Mobile account.  "Please stay on the line," etc.  I hung up.  What a crock.

received call from 3018610708 multiple times very annoying.

Don't ever answer unidentified calls. Let them leave a messge. They will get tired and stop on their own. It works for me all the time. Genuine callers will say who they are and leave clear messges and reason for calling. Bill collectors use unavailable, private caller and other unique codes. Golden rule: Leave unknown to unknown.
