MTN Service Delivery

Upgraded 4 contracts for my boss and his family. The one was delivered, which I signed for and the others were not forthcoming. When I contacted MTN, they told me I had to cancel the one already delivered so that they could cancel all of them to reissue, all of them. I said this was not acceptable and that they should have a waybill and tracking number and if the parcel has not been delivered, it is the senders responsibility and that they must just resend the 3 contracts and devices outstanding. It is not our fault if a courier does not deliver a parcel. MTN must come to the party.
