Worst service from MTN!

I opened a new contract with MTN on Thursday the 9th of June. Today is the 14th of June and I still can't make use of my SIM, as it keeps on saying RICA pending! I need my number for business and MTN is just sending me from pillar to post. I emailed customer service, which gave me a number to call for RICA (don't know how they expect me to call with a SIM that is not working). When I call the number, they advise they can't help, I must go into the store. The store says, head office must RICA the number, and they can't call them, they can only email, and wait for a response. In the mean while, who will be taking responsibility for my lost business. If I could give 0 starts, I would! This level of service is unacceptable.
