Who called from 3138795173

I get calls from verizon retention department from this number wanting me to press one or press two

Our phone number has been a business phone for 7 plus years but we still get calls looking for the former couple that ATT had at this number , mostly for collections.  We tell the callers if they leave a message or we speak with them the folks they're looking for are not the owners of the phone number they're calling and they stop.  The Verizon folks calling, looking for them give no opportunity to update their data base and I am growing increasingly annoyed at their repeated calls, 1-3 a day, for days on end.

Same thing. They say it's not a sales call, but...

And it's poorly automated, most of the times it doesn't hear us pick up and say hello.
