Had enough of MTN!!!!!!

For almost two weeks I have been struggling to upgrade a MTN contract. My father (a 76year old man) is the contract holder. He was with me at MTN the first day to give his finger prints and his old green ID book after which they told me to come back the next day to get the upgrade cell phone. The next day they informed me that I could not get it as there is an ID card for my father at home affairs that needs to be collected at first. (my fathers ID card was ****** and he still hasn't app**** for a new one) When we got to home affairs they said there is only his new passport. With that new passport we went again to MTN only to sit instore for 3 hours!!! Still no upgrade cause they wanted the new ID card!!! Today I got a photo of his ****** ID card on my cellphone so I sent it to MTN only to hear that now they need the back of the card as well. I cant even explain the BAD BAD service we got from MTN and there is nobody that can give us answers, there is no telephone number that we could call, nobody answer any of the emails. MTN we have two more upgrades coming up only in 2023 cause my father has a lot of contracts with you....maybe its time for us to move on to a service provider that could help??????
