On numerous occasions during XX/XX/2015 Diner Club Credit card hastaken an inordinate amount of time to post the monthly balance pay-off to our account. Generally waiting until after the duedate has past. When Customer Service was query more than3 time during XX/XX/2015, Service personal gave the preverbal the Post Office must be to blame. The demonstrative facts are quitedifferent ... 
Twice document, XX/XX/XXXX and XX/XX/XXXX, on the day the payment was due, and 15minutes before close of their business day ( PDT ), Diner Clubclaimed the payment was not yet received, yet XXXX ( EDT ) thefollowing day the payment was not only received by Diners, but posted to the account, and had cleared our checking account the nightbefore. As you can image this must be magic, how during theirbusiness day they have no real time information, but our check canarrive, be processed, posted to our account and miraculously clearour checking account, the night before. Sounds like very sloppyaccounting work flow and at the very least poor customer service.
