Pathetic Service!

I am very upset with DSTV, I just called the customer service center at 20:39pm trying to sort out my billing. I spent 43min on a call with 2 *********** agents whose are giving me misleading and wrong information. I have been paying R650/R600 per month however on the 3rd of June I was charged an extra R320, those funds were supposed to be refunded back to me. Which never happened. Today again I paid R650 and I was charged an extra R242,77 which makes no sense because my billing tells me that month on month I need to pay R524,57 plus R37,57 for Showmax. I NEED SOMEONE TO EXPLAIN WHY AM I BEING CHARGED MORE ???? WHY ARE YOUR AGENTS LYING ??? Your agents do not know what customer service is and they are uneducated! They can not interpret a simple statement. I need my money back for ALL the extra funds I have been charged for no reason!! Or else I am taking you to the OMBUDSMAN!
