Useless MTN

I took out a new cellphone contract telephonically on the 30th of September. I received the phone and sim on the 2nd of October from DSV, whilst the guy was busy chatting on the phone. Did not even says 2 words to me. he just made me sign, took my id copy and left. The sim card I have is Rica barred. I called DSV and they referred me back to MTN. I have been struggling with MTN for the last 2 weeks to sort this out. 1. I took the contract out telephonically for convenience, why should I be inconvenienced and go to a store to have it unbarred. 2. Someone failed and is still failing at their job and now it's my problem. I just do not seem to get any assistance from MTN. I have been transferred from customer service to retentions to activations and still nothing. Hopefully now someone will take me seriously as it's only when you complain you get action.
