Horrible Service

I have ricca a sim card on Wednesday 10 November 2021 On Thursday the sim card did not work I could not receive any calls or any SMS I could however make calls . I Phoned MTN's call center From this number, the option menu were zulu I could not understand this, then I phoned from my personal phone, I was told i was at the wrong department they will transfer me, 15 minutes of waiting and the call got cut , I phoned again and I was told that I have to phone the department. Just note that on the menu it says if you are phoning for a different number press xx when the operate answered I was told I have to phone from the number that has a problem. Explaining it was in zulu he said he will fix it . After phoning from this number I spoke to a operator that told me I should dial a certain *# number it will be fixed. I did nothing was fixed , I had to phone again they then said they will have to launch a ticket for the technical department and they will call me within 24h well it is 15 November more than 72H later and I had to phone them again. With a reference number I was told the ticket was never launched and that I have to call again in 24h. This is terrible service definitely moving to a different service provider . Almost 3 hours calling etc and nothing is solved!
