MTN deliver wrong equpment and then lost it

Upgraded 20/12/2017, with promises goods will be delivered in less than 5 w/days.When delivered (late) it was not what was ordered and the delivery was not accepted.Then the daily calls started,all with promises that they would call back.Even the escalation to the supervisor of the call centre Sibusiso,led to promises and he failed on each promise.The laptop was lost between DSV &MTN,how is this my problem?A month later, I have to pay for data,whilst waiting for you to get your act together?Theft. Nothing less.
