BAD SERVICE FROM MTN

On 03 August 2025, I signed up for the MTN uncapped wireless router. After the router was delivered, I did not open it immediately. I only opened it last week, on 15 September 2025. I struggled to connect until I got it right. But prior to that, I called MNT for assistance I could not get help. It connected one day only, and the next days it couldn't till today. I went to Vaal Mall MTN. I was told they will not be able to help, I need to call MTM 135, which not answered till today. MTN service is very bad. I regret signing up with them. Been using MTN for years but their service is very bad.
