Hello, I took out a PO Box in August 2012 which was directing mail as it should to our real address. Payment of ~£276 was also taken by Direct Debit in this month, but Royal Mail failed to allocate the payment to our account. In September 2012, Royal Mail cancelled the PO Box for supposedly non-payment, just before we launched a magazine marketing campaign costing us £2,500.00. We were expecting approximately 200 to 300 responders, based on a similar marketing campaign launched earlier in the year. When we got zero postal responses, we assumed that the magazine had dumped our brochures. With hindsight, we now know that customers with a return address would have their cheques returned. Customers without a returns address may have their letters opened by Royal Mail, and then either sent back to recipient or destroyed. My concern is for the waste of the original £2,500 investment, but also the negative light for the customers that liked our advert and sent in a cheque. I know if I sent off a cheque and didn't hear back, or received an 'undeliverable' notification then I personally would lose faith in that company. This is very hard to put a figure on. Royal Mail have accepted that payment was made, confirmed that the account will become active in 3 working days (7 weeks after the marketing campaign was launched) but have currently gone silent on the matter of compensation. Does anyone have any experience on claiming compensation for loss-of-earnings, or dealing with Royal Mail in particular? Any thoughts on the matter would be appreciated because this is new territory for me. Thanks, Alex
