Contract Cancelation that was never processed.

Been with mtn for years now but it seems that the service when it comes to the problems they need to resolve is the worst ever.

Good morning hope this email finds you well. Im getting a bit very annoyed with the fact that MTN is taking forever to sort out a issue they have caused. So about around 4 months ago i wanted to do a upgrade for my mom then found out its not the phone my mom wanted so i went in to do the cancelation.To find out 2 months down the line they haven't sorted out the process yet so the bill just been adding up on a phone I do not have in my possession and then when I went in to the branch they informed me they not able to have access to that process its the people higher up. So i been waiting for this to be sorted out because now im not able to do a upgrade or cancel data plans.In this case its now affecting my credit score and going as missed payments.

So i hope this issue gets resolved soon or i might just rather change service providers because it seems that the service is just getting worst.
