Ridiculous customer service

I would give a zero star rating if I could. I am utterly frustrated with the service at MTN. I received my data sim card on the 19th of January, to this day it hasn’t been activated. I called numerous times, sent emails with no luck. At this point I just want them to cancel my contract. If this is the service I get as a new customer I don’t want to see what it will be like once I’m deep in a contract with them.
