Poor customer service

I took two contracts with Cell C and along the way I had change my bank account which I advised Cell C on then I continued paying my contracts via EFT. However I made a mistake, I paid for both accounts using one reference number then my other account was in arrears and the other has a surplus.

I never received any phone call from Cell C to discuss this matter of a surplus but I received a phone call being told I'm on arrears with my account. This on its own shows how messed up their CRM system is as this should've been picked up.

When this was brought to my attention I contacted Cell C and the error from my end was identified and a case was open to get the funds transferred from the one account to the other and that was first week of Jan till this day, this matter has not been resolved. My credit score is being affected by this as I was also due with them for an upgrade but due to the negative reflection I am unable to get a phone.

What irritates me most about this matter, I will speak to a consultant and they I'll be all nice and give me hope that this matter will be resolved two weeks later when I do a follow-up I discover nothing was done.
