Horrible DSTV Price Lock !

Hi

I purchased a price lock in Oct. I never installed or used the decoder as my building could not accommodate the new decoder, also I have a premium account so I was fine. I have been calling dstv since Nov 2017 and the second call i made , a agent assured me that my account could be cleared since i did not use the service . I have called ever since to cancel my account , i am still being billed on something i have cancelled and have not even installed. My calls just get escalated but no one calls , or when they do call, its a month later due to a back log. Someone fix this now! I have used the same number for all my calls, so the agent can be traced who promised me this.
