MTN router

I bought a mtn router uncapped home internet from MTN and it was delivered on the 26/11/2024. My router has never worked and it has no coverage since the day of delivery. I called mtn regarding my problem and it has never been resolved, I called them almost every day since the 26 of November. I called them again yesterday only to find out that they send me a wrong router. This is very bad service from MTN.
