MTN hates it's customers

They are not trained very well, when you go in store they tell you to call 135, when you call 135 they tell you to go in store. MTN does not like it's customers, they treat us like ****. I am not sure on the other networks but I when it comes to MTN they are possibly the worst in my experience. Also to bring up old wounds they stole a few thousand rands from my account a few years back when they where changing billing systems. I would like to active my esim on my watch apparently MTN does not offer this service?
