Incorrect billing

In July 2015 my account balance according to dstv was R34,00 to be paid on a select 1 package that i have. I then made a payment of R1035,00 essentially paying the account 5 months in advance until January 2016. They then decided to cut me off. Then it became a long debate as to weather i am using the decoder in or outside South Africa as i'm working in Mozambique but my family who are in South Africa are using the decoder. I eventually got them to understand that this was the case after a number of mails and a report on Hello Peter. Two weeks later someone at dstv decided to activate an inactive premium account that i have not used for more than a year and billed me for it. I sent more mails regarding this issue as i gave no authorization for it to be activated (They can check their RECORDINGS). They have subsequently deactivated the account but still billed me for their mistake. Now because of their issues and my account now being over they have disconnected my subscription again on my smaller package. I will now no longer deal with dstv and will approach my attorney to advise me on further action against them.
