MTN: "the number you have dialled does not exist"

[hellfire]

I've had a few complaints from people trying to call me that they get this message.
I'm on MTN.
Any idea to which department at MTN I should escalate this?

I'm sorry but that number does not exist.

Had the same issue. Contact porting department. They need somehow reload you onto the network.
