Don’t speak just hang up

I picked up, sounded like a call center in the background. They hung up without saying anything.

Caller: ??

Called, I answered, background noise and they ended the call. Likely scam.

Scam

Caller: Super review services

Called from a mobile, I was expecting a call so answered.
Said they were super review services and got really pushy and rude when I wouldn’t tell them how much super I had. I hung up.

Caller: They said it was to provide a super review

When I said I was not interested she became rude and aggressive. I was nice but after the third 'no thanks' lost it!

Same as above. Scam of some sort.
One time they said heelo. I told them they are a nuisance . They hung up.
I said hello and there was no sound, they hung up.
They don’t speak just hang up

Caller: Unknown

Called twice from this number and hang up straight away both times. Block this number

Ive been called a number of times by this number. It shows up as " I this " in call recognition.

If you answer with or without voice, theres no reply.

So, having decided " I am over this" I have blocked the number.

I answered Hello and they hung up. I could hear like a call centre in the background.

Scammers dont answer

Caller: No identification

This number has called me on three consecutive days, each time I've been fortunate enough not to have answered the call. I do call back as soon as I have seen a missed call, the call goes straight to message bank with a robot cheap as computer voice counting out their number then inviting a message to be left. I've left two messages to call back as I'm trying to sell a major item on Gumtree. Maybe? this is the link/connection to these calls? Nuisance call at the least.

Sounds like a call Centre. Hangs up after a couple of seconds.

I said hello and there was no sound. I said hello again and then hung up

Caller: Super Review Services

Scam call. They have called me know at least five times, each time from a different number, and do not like being told that I am not interested (anything from rude outbursts to simply hanging up on me). I have asked to be removed me from their contact list, the last caller claimed that they can only call once and if refused never call again. Clearly not true. Scam through and through.
