INCOMPETENCE - WORST SERVICE PROVIDER EVER !!!

Good Day I have been an MTN customer for 2 years now , July 2020 my 2 contracts were expired and I decided to cancel the one and upgrade the other one. What a nightmare I do not even know where to start. The problems started with my upgrade which was done on 2 July 2020 , everything was confirmed and was promised I would received my new device 3-5 working days so I phone in the following week no one can answer my questions as to where the phone is. Finally I get through to a consultant that know's what he is doing and he then tells me he does not know why I was not informed but the Warehouse has been closed due to Covid-19 ( okay all understandable ) and I was insured that I will not pay for the contract if the courier has not delivered it yet. Finally the DSV mounties has the phone another 7 days before it gets to me eventually on the 22 July 2020. Suprise Suprise I get invoiced for the full month after fighting a battle I then decided is not worth it anymore I pay the invoices sent to me as per usual EFT on the 25 July 2020. Today 7 August my sim does not want to work so I phone them , your services have been suspended due to no payment and handed over to legal so now I have to wait yet another 48 hours for the to look at my proof of payment and activate my sim again , this affecting my credit score and not having a working sim all due to mistakes on their side. BY FAR THE WORST COMPANY AND SERVICE EVER. I WILL NEVER EVER DO BUSINESS WITH THEM AGAIN MY HUSBANDS CONTRACT EXPIRES IN TWO MONTHS WE WILL BE CANCELLING.
