CLOSING OF ACTIVE PAID UP ACCOUNT

WE HAD A ACCOUNT WITH GAME STORES WHICH IS RUN THROUGH RCS, WE HAD A CREDIT LIMIT OF R17000.00 I PAID MY ACCOUNT UP LAST YEAR, AND PAID A EXTRA R10 TO KEEP ACCOUNT ACTIVE. WHEN I WANT TO PURCHACE A SWIMMING POOL SUNDAY AT GAMES THEY SAID MY TRANSACTION WAS DECLINED, WHEN WE ENQIRED ABOUT IT THEY CALLED SOMEONE WHO SAID NO OUR ACCOUNT IS CLOSED SINCE WE DID NOT USE IT, SO HOW BAD IS THAT, THE LEAST THEY COULD HAVE DONE IS SENDING A MESSAGE SAYING IF YOU DONT USE YOUR ACCOUNT WE WILL CLOSE IT. THIS IS VERY BAD CUSTOMER SERVICE.
