Cell C suck!

In Noverber 2019 I contacted Cell C to inform them that the bank account we were using for the Cell C debit order was closed. They gave me an account number for Cell C to do a cash payment at the Nedbank ATM. I also informed them in writing that I will be paying my monthly installment via EFT from a different account. The installment for Cell C has been paid for the last 2 months via EFT. Friday the 7th of Feb 20, Cell C stopped my wifi. I phoned the call centre, they told me that I was in arrears for 2 months. They also charged me an extra R70 for the debit order not going off.... They gave me an email address to mail my proof of payments to. I did send the proof of payments. Saturday the 8th of Feb 20 I went to the Cell C branch where I do my business. The lady also asked me for proof of payment, which I emailed to her in store email address she told me not to worry as this will be sorted out by Sunday. Su day nothing happened, I phoned the call centre again twice. Both times I was just cut off. Today, Monday 10th Feb 20 I phoned the call centre again, the lady put me on hold for more than 15 minutes to check up on the proof of payment. I eventually changed up. I phoned then back and spoke to a gentleman. He, very rudely told me that I am I arrears and I need to pay the full amount before the can reconnect my line. I explained that I am not in arrears and that I did email the proof of all the payments through to them. At that point I was really upset and used the sh*t word, where the gentleman told me not to swear at him. I hanged up. Plus minus 3 days, all my MYN phone minutes spent on Cell C and up to now not one call back from them. They claim that there is no emails from me with the proof of payment. So I think Cell C SUCK!
