Don't use Mondo,terrible service

Absolutely atrocious customer service, I received my MTN SIM card two days ago and it is yet to be activated. I call in the customer care line and I am put on hold, the call suddenly disconnects after waiting for 20mins. I try calling back and the call continuously gets cancelled. There is no one I can speak to or ask when my SIM card will be activated? They also say I can cancel the contract within 10 days, if this is how they behave I highly doubt that's a possibility. I have been trying to get a hold of a service agent to no avail. MTN is no better, to get through to a customer service agent is next to impossible.
