I called back number (03) 8740 2197 rang 3 times then goes to busy tone.

I answered this call and it was someone who claimed "they could save me 42% on my energy bills." They said "If you don't mind, please provide us more details about your energy provider".

I said I do mind and I would like to be taken off the contact list and they disconnected me as quickly as possible.

DO NOT provide any details, even personal details to them.

I’ve received two calls from this number. No one I know

another stupid call center I imagine...

They have rang me 3 days in a row. doesn't leave a message so I'm not ringing back.

Asked me about my electricity, advised I was 16 they hung up.

They have rang 3 times and always hang up. Can't be connected or busy tone when I tried to call it.

Cannot ring back, receive busy tone when ringing from mobile and receive all lines to the area are busy if you ring from a landline. Nuisance call

Spam!
