Fnb no help after 4 months, terrible customer service.

In Dec 2018 I upgraded to fnb premiere banking unaware there was a 199.00 per month payment for the service. In Jan 2019 I called to have my previous account reinstated and cancel the premiere account. They said it would take 7-9 working days. That was 4 months ago. Many phone calls visits to the branch, emails and communication via fnb app and I am still no further down the road. Every month they charge me 199 and I have had enough. I just want them to cancel the premiere account and reimburse me for the 4 months payment. This isnt rocket science. Why can't it just be done? One guy said they can't contact me as they have tried calling, so I gave him my number again, in case they have the wrong one but still have had no calls. Today I tried calling the helpline and the premiere helpline and both just get cut off as soon as a consultant answers. Sounds like they don't wish to talk to me. My emails go unanswered. The physical branch says I have to direct my enquiry to them, so they cant help. How do I have any recourse? For a bank this size their dealing with people is abb****nt. Unhelpful. Unsatisfied. Ex-customer. Don't use them. Go with capitec. At least it seems like they care....
