BEWARE SOUTH AFRICA !!! DINERS CARD WILL BE GOING OUT OF BUSINESS

IF DINERS CARD CARRY ON LIKE THIS THEY WILL BE GOING OUT OF BUSINESS. I RECEIVED A STRANGE EMAIL FROM THEM ABOUT A TELEPHONE CALL WHICH WE NEVER HAD SAYING WE DID NOT FILL IN AN AFFORDABILITY REPORT WHICH WE NEVER RECEIVED AND SAYING THAT OUR CARD WOULD BE CUT OFF. I HAVE NO IDEA WHAT THEY ARE TALKING ABOUT. I HAVE BEEN PHONING THEM EVERY SINGLE DAY AND EACH DAY I AM TOLD MEMBER SERVICES WILL CALL ME LATER AND THEY NEVER DO. THE EMAIL IS ADDRESSED TO US PERSONALLY SO IT IS NOT SPAM OR ANYTHING AND DOES NOT EVEN GIVE THE CARD NUMBER OF THE CARD IN QUESTION. I HAVE JUST TRIED PHONING NOW AND THERE IS NOBODY ANSWERING THE CALLS. WHAT IS GOING ON WITH DINERS CLUB SOUTH AFRICA? IT SEEMS AS IF THEY ARE DEFINITELY GOING OUT OF BUSINESS. TIME TO CHANGE TO AMERICAN EXPRESS ???
