Ongoing billing problem

<p>I renewed our DSTV subscription as per an email I got from DSTV telling me to renew before 1 April for a year and only pay for 11 months and renew at 2015 prices. Our subscription runs from 27 June to 27 June, but on calling the call centre I was told we can still renew. We paid for the full year, and DSTV renewed only for 9 months, and gave us a credit for the last 3 months. They will not renew for 12 months as per the email to us. The issue is that the subscription will increase next year, and the credit will not cover the increase. No explanation has been provided as to why our renewal was not processed as 27 June to 27 June. I have been querying this since April, and cannot get it resolved</p>
