MTN Home router Nightmare

My home router stopped in March 2025. I have log calls repeatedly but never received any assistance. Was then told by MTN CityView, (Dbn) that I needed to upgrade. To date I am paying my premium however that router hasn’t worked, post the upgrade and have been promised that it will be fixed. I have called and went into the branch since March to date but still nothing. I then cancelled in October and then was told that I still need to at till the end of contract, for a router that has not work. Call centre says I needed to cancel and re-instate… reinstate a product that I have been paying for 8 months and getting no service from
