discussed with service

Have been waiting since 8 February 2023 for my upgrade from Summer Mobile. They did not contact me to advise that the delivery address is incorrect, I had to phone them. Phone them twice already to change the delivery and still nothing. Contacted again on 8 March to cancel the upgrade and they cant cancel it due to system error, had to log a call with MTN. 14/03/2023 - no ticket logged, logged again. 27/03/2023 no ticket was logged MTN them selves cant even get though to them. Hold on for hours to get through to their line. Almost two months and still no joy. MTN cant assist due to the "Service Provider" that has to cancel it from their side. It is terrible that MTN can's even resolve a query with their own Service Provider.
