DSTV and Showmax are just useless

I had a DSTV streaming package which offers streaming to one TV and a device until 24 July, this service also included Showmax for free on the premium package which was working perfectly. As of 24 July I did not renew the DSTV subscription. On 4 August I purchased a DSTV explora decoder and connected the premium package which allows you to view one TV off the decoder and a 2nd TV connected by streaming. This package also includes free Showmax. Since switching from streaming to the decoder I have not been able to connect to Showmax. When trying to connect a message indicates that I am not subscribed to Showmax. I have sent no less than 15 emails to DSTV and have had several telephone conversations with them but to no avail. Their last suggestion was that I contact Showmax. I did this and have sent and received numerous emails with Showmax but I still cannot connect to Showmax as when wanting to connectit indicates that I am unsubscribed. Do they not realise that they should remove all previously subscribed accounts as I am still linked to an unsubscribed account. I have advised them this on so many occasions but they just do not understand
