I work at a business and when I answered the phone they hung up.

they call multiple txs a week and never say a word.

they have INTRUDED in my life on a number of occasions, taking advantage of the service i pay for which provides ME with all said benefits (my phone).

My phone service (cell included) is kept in place for MY convenience, not anyone/everyone else's.

however, on one specific occasion, recently, the offending party must not have heard the voice mail prompt (???, as i speak rather ... it's hard to miss.

subsequently, my voicemail plays back a mildly confused woman, repeatedly asking into her end, 'hello ? hello ?

not much useful info, but an update, all the same !!

This phone number calls me on my work cellular at least once per day for at least two months now, and every time I answer, they hang up.  Today I answered the phone with just a hello this time, and after a long pause, someone asked for "Curtis" - I told them they had the wrong number, and then they hung up.
This is getting frustrating!

This is a collection agency looking for someone with the same last name as the number they are calling.
This number calls every day, and I never answered until today because I'm fed up with them.
I got a recording that said "This is about an urgent business matter, sorry for the delay", which repeated for 1 minute until they hung up.
So I called back and it sounded like CBV Collections, who are looking for Michelle with my same last name. They removed my number from their list since I don't know who Michelle is.
They obviously kept calling, because they think Michelle is here avoiding to pay her bills, and I don't answer thinking its telemarketing. Sometimes you got to talk to them to see what it really is about.
