Account Billing

Dear MTN,

I would really like to conclude my query, its getting tiring that I always have to write and require clarity about my account and in the end I do not get help, again my bill is incorrect for December statement, my second phone the ********** is incorrectly billed for R299 whilst it is suppose to be R89 cause the upgrade was cancelled, please people can we really get it right its a New Year, I honestly would not want to still continue with this incompetency in 2018.
