billing information

<p>I had a contract with altech autopage which then migrated my account to mtn in march 2016. The problem I had with mtn was that I paid my account for the month of April & May & when I check my statement it always shows an outstanding amount of both months, I firstly phoned customer care & I was told that I paid into the wrong account which is autopage instead of them whiles I got my account details from mtn which I used to pay my account, I then sent an email in May & June to rectify this & I was told to submit proof of payment which I did & was told it was sent to the accounts department BUT up to this day it is still not fixed. I am sick & tired of always having to send emails about my account & yet nothing gets done. I never had problems with autopage for the past 4years I've been with them</p>
