They ring any time of the day or night and don't give up. Over and Over

I answered & it was a Call centre .

Caller: Something like 'Chorus's Please'

Rang once or twice a day for a week. Eventually I picked up. After trying to understand who was calling I asked what they were selling.
Telemarketer: We are not selling anything. Do you want to make lots of money.... (I stopped listening)... blah blah blah
Me: (Very polite voice) Could you please take my number off your call list. (I had to say it twice because she was giving me her spiel).
Telemarketer: (Very harsh voice) NO!
Me: Hung up and blocked.

They disconnected call when I answered.
Called from several different numbers
(03) 8904 8730
(03) 8904 8732
(03) 8904 8733
