020 4549 4950 Negative Who called me from this phone number?

Silent call

usual scum bags trying to rip people mainly pensioners

Said they were the "local energy advisor for your area" 2nd time this person has called, blocked the last number they called from and told them not to call back, and yet they called back. Blocked this number and once again told them not to call back.

She's rang many times - Says, Hello my names Jo, ringing regarding Energy and asks 'are you the homeowner' we're a Business so I say 'No', then she puts the phone down on you. I rang her back to say please can you stop ring us, take us off your list as you keep ringing us and putting the phone down after I say 'No' to being the homeowner because we're a Business - She says 'No' and puts the phone down AGAIN.

They have several numbers to call. And call many times. We can not call them back. Financial Marketeer.

financial marketeer. Said I was on their system. I asked to be removed and they basically said, It's not my job' hung up

I have never given out the number they called me on, used it for over 20 years......so this must be a scam as they are just dialling through numbers sequentially, typical sweat box call centre used for these techniques....I have worked with large international corporate contact centres so know hows this unscrupulous bunch works. Wanted to gather lots of person information, which was not given, when asked about GDPR.......the line went dead. You have been warned

Makes sense

Missed call, no message, went to call back and dead tone.

I can only presume it’s from a cryptocurrency telemarketer
