CUSTOMER CARE and ACCOUNTS are NON EXISTENT and YOUR CARE LINE 083135 has been broken for 2 MONTHS!!!!!!!

MTN service is a disgrace. Firstly their customer care contact number of 083135 does not work and has been broken since November 2019 and today is still broken 7 Jan 2020. I formally took over an MTN account from my mother 1 September 2019. We both went into the store, ID books and signatures etc. My mother still got billed after that and I had to then pay her back. I went into the store at the end of September and they told me their systems were offline. I came back the next day and it was still offline. 3rd day it was back online and they told me the transfer of account was unsuccessful as my mother's ID book had her new surname on after remarrying and did not match the original one they had on file. NOBODY contacted us. So back we went and did it all again 5 October. Thereafter BOTH of us got billed. Myself and my mother. I could not get it sorted out and went into the stores on multiple occasions and nobody was able to assist me efficiently. It happened again in November. I was so sick of it went back into the store, requested to cancel this contact. They contact was due to cancel 12 December. I requested to cancel early. The original debit order each month was R612. I then canceled and ported my number over to Vodacom as they had better customer care. I got billed R935 and my mother got billed R400 after that! I was horrified and went back into the store, I was told that MTN billing is done a month in the past. The R400 mom was still debited had to do with the transfer of account. The R935 I was billed was the account and including the fee for porting over the sim to Vodacom and for the few remainder days left on the contract as I canceled early. I just accepted it and thought well at least this painful experience is over. It is now January and I have just been debited R967 for MTN again!!! I went back into the store and now they no longer have an open account for me so they can't access it at all and all they could do was log a ticket and was told someone would contact me the next day. Nobody did so I called the store directly and they said sorry we will just log another ticket for you. Im yet to resolve this. It is astounding that your customer care line has been down since November and that after so many trips to the actual stores I am still unassisted. Your support department is useless, your accounts department is useless and your service is useless. This is exactly why I moved to Vodacom. Not for a better deal, but for better service. I would LOVE someone who actually can access my account to contact me.
