Caller: I don't know

This number called my mobile and I didn't answer as not on my contacts list. It went to message back and when I checked the message was "Hello" and then hung up.
As no decent message was left I would call a scam of some kind.

called me tonight similar to prev comments - hang up

Caller: I don’t know

They call and hang up !!

Called regarding reducing bills. Asked to deposit money before they could help.
SCAM

Caller: f*cking Indians

sh*t heads calling me several a week. Discount on the bills or some sh*t.

f*cking morons don’t even understand when I say shut up and don’t call me.
I wish I could get to them to give them some discount from my side
