Mailbox picked up ******* leaflets to advertise my optical practice. Despite MANY unreturned calls to them, mailbox never delivered them. Only when I got Trading Standards involved did I get my money returned. I never got my leaflets back and received no compensation for their loss.
Although they were very happy to take payment by credit card, they would only refund by ( very delayed) cheque.
I found them to be unhelpful, evasive and arrogant.
Do not trust them!
