Block this number at all times

Called about getting NBN in the area and to arrange a consultant. Likely another scam. Do not give out your details to them, and just block them.

This number called me selling something and I said “no thank you please take our number off your call list” and hung up. He then called back and said “fu*k off” and hung up. When I tried to call the number back it goes to busy tone..???

Told me they were NBN Smart Talk in my area told me they will have a consultant call me I told them no thank you dont have anyone call me at this time not interested. He then told me I was rude, I said you called me how am I rude. The next call he said I want to talk to the rude person, the 3rd and 4th call then called said "you are rude" and hung up. BEWARE AND BLOCK THIS NUMBER
