Stop spam calls

Caller hung up when I spoke.

When you get a telephone call like this ask for the company registration number or VAT number surprised that the answers you get these are nothing more than scammers trying to get hold of your information never admit to anything and never say yes to anything just keep asking for the company registration number and VAT number they tend to get very upset and put the phone down

Can't return call. Probably sales call?.

Silence.
