DSTV RUDE AGENTS AND MANAGERS!

What a bad experience I've just received from the call centre I called in wanting to find out why has the amount went up from R360.00 per month to R410.00 per month the first agent told me it's a system error I asked to speak to the manager she put me on hold n didn't call the manager. I called the 2nd time to speak the manager the guy told me he will assist if not he will call the manager I explained to him what's happening he checked the records and confirmed I've been paying R360 for all the years I have been using the explora then he decided to put me on hold so that he calls the available manager.. BOOOOM guess what after holding for about 5-10mins the guy said thanks for hold I did get the manager how ever before he talks TO YOU HE SAID I SHOULD TELL YOU FOR ALL THE YEARS YOU HAVE BEEN PAYING R360 IT WAS A PROMOTION I rep**** how possible it is that ever since I started using the dstv explora it was a promotion HE REP**** THAT'S WHAT IT IS. I AM VERY FRUSTRATED AND ANGRY DSTV IS SKAMING US AND NO ONE CAN EVEN ASSIST. I WANT MY MONEY BACK!
