Dstv multi choice sucks

Honestly I'm disgusted and frustrated. Last week I called Dstv to find out how much is due for my debit order since the WhatsApp number says my amount due was R0.00 ... The agent I spoke to said there's a credit on my account so I decided to upgrade from access to premium. The agent said I received a discount and I'll only pay a balance of R253. I agreed. The next day I checked my balance on WhatsApp and it said I owe R350. I called them back and said I'm not happy because I didn't have that amount kept and to downgrade me to a package that will be covered. They put me in compact plus. From there they said I'll pay approx R200 I said okay . They next day I checked my balance they said I owe R870. Frustrated I called back they did calculation and said I owe only R57 . my debit runs on the 15th and it never went out so I called back to find out what's going on. They said it was a system error and they will debit... They didn't . I called again they said it's balanced there's no debit for this month . I said okay fine. This morning I woke up to see R671 Debited of my account and since there wasn't enough funds it bounced and I was left with bank charges for a bounced debit of R133 since I bank with fnb. I called this morning the 1st agent was completely clueless and I cut the call and called back. I spoke to an agent to escalated my complain As I asked for a discount on next months debit since I called so many times and had to pay the extra fees for their incompetence. I'm still waiting for someone to contact me as she made a note for someone to call me back regarding this matter.
