MTN Direct has no communication etiquette

MTN Direct is very eager to process an upgrade but not so eager in doing due diligence. After providing correct delivery address and contact number, I had to call multiple times to follow up on where my device is. Just to find out that the number the delivery service was given was a wrong number. (This is after giving the correct number and confirming the correct number and address multiple times) Again I called MTN Direct again today to speak with the consultant that assisted me after she was said to be back from lunch and still to no avail do I have an answer or solution to this. When I now call back, the phone stays on hold and just doesn't get through to anyone. So I can't even follow up to see what is going on and why my delivery wasn't done.
