I called back number (07) 3703 1786 rang once then gets disconnected automatically.

I didn't answer. No message left.

after answering, a voice says "Goodbye" - tried calling back, it hangs up straightaway upon answering

I think spam

Spam, total waste of time!!!

Scam

indian drug dealer

When I answered they said goodbye and it was a recorded message

Called about changes to electricity prices from an overseas call centre. Do not bother!

Keeps ringing me is indian scammers, they should f*ck off

trash humans, not legit

I’ve just seen my own post re this number, thought blocked but obviously not! I returned call a second after it stopped ringing but it says ‘call failed’!!
What do these idiots want? Voiceprint?
Absolute pests!!

Caller: Indian Call Centre

Power spam

I’ve posted something previously re 07 numbers...they keep on coming. I think Smart Energy or a charity, but if you return the call the number’s disconnected! Just a nuisance call!! Blocked

Keep getting ‘nothing’ calls from 07 numbers. Never leave a message. I returned call once to hear that the number was disconnected!! Pests!

Caller: Unknown

They rang twice but on calling back it is 'user busy'

Just disconnected.

I answered, then after several seconds of pause, just a "Goodbye" and then the call ends. Calling back is pointless, the call is hung up immediately.

Caller: Scammer

Potential fraud
