MTN Poor Service from day one

I had ended my contract with Vodacom, deciding to go with MTN, and from day one they gave me sh#t service. First of all, they said they would deliver in the first week, but they only delivered in the second week. I forgive them for that one. But they continue to disappoint me. They delivered the SIM card, and I was advised that the SIM card would be active within 30 minutes. It's almost half a day, and the SIM card is still not active. When I called their customer care, I spoke to Sihle, and she advised me that she could assist but did not even bother to check my profile. I am not happy with MTN at all.
