TERRIBLE BAD SERVICE AND RUDE CONSULTANTS

On the 4th of March 2021 I paid my MTN contracts account with my Capitec app on my cellphone.The amount of R755-00 was paid into their MTN Contracts acc at FNB bank.It reflected in my account and showed the money is out of my account into their account.I then send them proof of payment.They rep**** by telling me they cannot accept the proof of payment because they cannot see date when payment was made,the ref number and the amount that was paid.The proof of payment was sent to them on 5/3/21 (01:58AM).On the 9 & 10 I send them more mails as proof of payment after speaking to their consultants.In all this time I was busy trying to sort them out my mother passed on and 2 weeks later my stepfather passed on and I could not use my phone and the account was paid.I tried to explain to them I do Bio Security work on 2 farms (nightshift) on I cannot work with a phone of which the service has been terminated.I went to Capitec Bank in Heidelberg Mall and got a letter as proof of payment and took it to the MTN shop.The lady uploaded it on to their system and said I must wait 48hours.After 48hours my service was still suspended.I went back to the shop in Heidelberg Mall.I live in Villiers.When I got their the lady said she cannot help me her system is offline I must phone customer services.I went home phoned the customer service consultant explained my story .She said when the call has ended I must restart my phone and the service will be restored.I did it more than once with no luck.Phoned them back and the consultant put the phone off while i am busy talking to her.That night I phoned again and the lady helped my and the line was restored.On the 6th of April they send me a message I owe them R1412.19 and if I dont pay it my services will be stopped within 1 day and they are going to report me to a credit burea.So I phoned them and asked tem to send me an account so that I can see where they get that amount from.The lady mailed me an account for R648.77.So now i am confused.I left it.On Friday 09 April 21 they send me a final notice I must pay R8934.31 for the full contract and they are taking legal action against me and they are going to blacklist me for that R1412.19 that is outstanding.So I phoned them again and asked them to please explain to me where they get that R1412.19.The lady told me it is that R755.00 that are in arears which I gave to them personally in their hands plus the account for March which I told them I will not pay before they fix my problem.Now they want me to go back to the shop in Heidelberg and take them another proof of payment from the bank because the previous one wasnt uploade on their system and they have suspended my service once again.MTN ARE THE WORST.
