Mtn call centre phones do not buy its not worth the headache

Call centre from a devision of mtn call to cell a phone contract. Honor x5 I received the phone could not keep my number, that was the condition. Cancel and return the phone via courier company, they never received the phone. Get a bill for a phone I don't have. Get email threats to pay. Sit hours on the phone from 1 department to the other still not resolved.
