Sim swap not active after a week

I have been trying to get my new contract sim activated for the last week. I have phoned it and also gone into one of the outlets however with no luck. Evertime I call in they tell me a different story and every day they say it will only be active within 2 to 24 hours. However it's been 168 hours and it's not how you do business. I regret to say that virgin mobile is far better than mtn at this stage. I have been with mtn for the last 13 years and this the first time I have been experiencing anything like this from then. There service has dropped a lot an it really very sad to see this happening. I will not again go with mtn... MTN why can't you keep up the good work that I received in the past.. It's very disappointing to say the least
