This happened to me once. One of my previous employers insisted on the use of a Diners Club charge cardfor business travel. “The Card No One Accepts!”, we’d joke, as few companies WOULD accept it. “High merchant fees”, was the excuse a retailer would often give.
Anyhow, our “awesome” accounts department failed to process an invoice on time, so I got hit with a charge for $39.34.
Since then, I maintained a positive balance on my Diners card.
But the really annoying thing??? When I closed my Diners Card account, the bastards at Diners refused to pay me the credit balance.
Oh yes, after all these years, it still annoys me. It will be a cold night in Hell before I ever have another Diners Club Card.
