Keep switching my service off

In February 2017 I scheduled disconnection of service with Dstv since we were leaving the country for some time. On return and attempting to reconnect it was found that the service was not suspended and that a pro rate amount was billed to my account. The call centre staff immediately requested a credit and reconnected my services in mid March. Since then until now being October I had to phone at least once a week to have services reconnected since the financial and administrative office seems unable to perform their duties and finalise the matter. All call recordings are available and each time I need to go through the 10min explanation again. The call centre operators are stars and have been trying for 7 months to get the problem sorted out however with no success. The costs incurred in time and telephone calls are astronomical not to mentioned the frustration caused. I gave even logged a complaint and enquiry on the website and didn't received as much as recognition thereof. The level of service received from the administrative leg of this huge organisation is shocking to say the least. Being at my wits end with this situation a require resolution of this matter immediately.
