Caller asked if I had received £500.00 voucher which had been sent to me.Scottish voice asked for me by name. Any other people had the same call. I put the phone down after saying I didn t know what he was talking about.
It might not be a 'scam', per se. It could simply be a sales ploy. (e.g. either you really should have received a £500 voucher or they'd be happy to send you one. However it's for £500 off the cost of solar panels, or similar, which are over-priced by at least £500 to start with).
