Unacceptable service from Cell C

I have been a customer of Cell C for many years. I never had any complaints and always received great service. Well lets say up until last year July 2021. According to me, my account is up to date, with a little bit extra. When I make a payment to Cell C, I send them the proof of payment. How ever I have been cut off, and with a few phone calls I was on line again. Then it happened in October again. Speaking to a person at Customer Care, noticed that the payment I made on the 1st of October has not been allocated yet. That was fixed and I was on line again, but then it happened in November again. Plus the email you send the proof of payment too is full and request you to try again - seriously??? From there my phone was never connected again, speaking to the one consultant to the next, all promises and no feedback. I have been sending all the proof of payments since June 2021 to every single one, then waiting for the payments to be allocated. On the 31 of December 2021 I had a breakthrough but 4 hours later I received a message that my phone line has been terminated due to non-payment. I just about lost it. Here I have all the proof I have and that I have send it to several people at Cell C - so my question is, who is not communicating with who? Phone call after phone call, email after email and all I received at one point I was requested to buy a new sim card and RICA it and send them the details and one other email that said they are so sorry for the inconvenience but the payments are still being allocated. How long does it take, seriously, how long? a Month and a half passed and its still not being allocated. Last week I received and email that I would be contacted in the next 24-48 hours but here I am, still waiting. With every phone call to customer care the complaint will be escalated. I'm paying for a service I don't even receive, paying for data and airtime that I never received. If I had to treat my customers like that, I certainly won't have that business for long
