Sometimes customers try to cheat a retailer by denying a credit card charge. Typically, such people are amateurs at the game and well over their heads. But when a long distance phone customer denies the charge, many retailers are left looking for a friend. The acquirer, whether ir be Paymentech or Monex, is neutral in the matter. They just do what the credit card company tells them to do. Both Visa and MasterCard are indifferent to the retailer. They will debit your account for sure if you can’t prove unequivocally that the charge is genuine. In addition, the card companies, Ameerican Express in particular, have a reputation for favouring the cardholder. In this bleak situation, retailers can rely on the Post Office to be a good and practical friend. If you mailed the parcel and asked for a signature on receipt, your case is a good as won. If your customer continues to deny he/she got the parcel, the Post Office will launch a lost parcel investigation. The stinger here is that the recipient is required to confirm to postal authorities that the parcel was received. If he lies, it’s called Mail Fraud. This spectre is usually enough to make the most determined cheater back down. At the bottom of this diligence by the Post Office is the concern for its reputation as a reliable shipper. So the Post Office is your friend.
