PAYMENT WAS NEVER PICKED UP

0n the first of September my DSTV was disconnected with the reason being I have missed a payment .I went to the nearest outlet to submitted a prove of payment. for that mouth. An email was sent TO HEAD OFFICE accounts Department and my DSTV was then connected, since then up to now my account has never been up to date. I am expected to pay the reconnection fees and subscription fees that I don't understand for which all the reconnection was done because of the subscription fee which was not picked up by their own system. it was their own mistake, It happened previously where I had pay the amounts which were outstanding due to their mistakes. They are now doing it all l over again. Its high time now they consider the proves which was submitted and update their system
