unhappy about service based on contract sim swap for two weeks without any resolition.

I really not happy with the service i receive from mtn.i have cellphone contract with them and for the past two weeks i have been calling and visiting store for this to take place. I dont get help but when you guys deduct from my account no problem but interms of service i dont get what i pay for. I was supposed to get data, sms and minutes on the 12th this month but is not possible as you guys to this point i cant get help i need. This service is not acceptable at all. No TCF on this whole thing. I payed for that sim swarp to be done after all of that i am told stories that sim swap failed. Client service is useless also because if is not possible for me to get help from store i am supposed to get it when i call contact center. I am told i need to go to store. Store i am going to in Park Station the only person who can do that is only one person. If this person is not at the store we are told we need to come next day when this person is available. If this person wont be available for a week on that store, this means for that week people who needs assistance on the same problem will always be told to come next day next day.
