Bad Bad Service

I'm very disappointed in DSTV Multichoice, last month I paid on the 2nd of February (my premium date is the 7th of every month), but my payment was redirected to another account, I thought it was my mistake, they managed to do the inter-account transfer, I was disconnected and they manage to restore my service, and I'm charged R50 for that, I'm not gonna pay that back, I will cancel my subscription if I have to I really cannot let these big corporation abuse me. This month it is happening again, I just paid yesterday, 06 March, the account deposited is still not cleared, I was using EFT it supposes to be showing by now, I have been trying to reach them no one is willing to help, they waiting till they can disconnect me again and charge me that R50 for their ****ups.
