Mnt service

I took a phone on contract November 2023 and within 2 days I noticed that there was a problem with the battery, went back and they said it's the settings and they changed the settings, went back the following day cause there wasn't any difference and they took the phone for a warranty assessment, this was on the 1st of December 2023 and they said it will take 1 to 2 weeks to get the phone but cause it's still a new phone, it could be less than that. Week 3 I went to find out what was happening cause no one was giving me feedback and they said the technicians are still busy and they'll get back to me before the end of the week, there was no update after that. Went again and it was another story, I was told the warranty assessment could be approved and I'll be given a new phone or I won't be approved and they'll bring back the same phone and if it still has the same problem, I'll have to book it in again. It is now over a month without the phone, it's stories after stories. I'm greatly disappointed with the service I've received at mtn. At this point I feel like canceling that contract because I've honestly had it with the excuses and the run around
