DSTV PREMIUM UPGRADE

I won a dstv premium upgrade and my nightmare started. They blocked all my channels and asked me to pay for a service which they upgraded automatically on their side. They are now saying the Promo is over I have to pay but they are the ones who upgraded me. We spoke to a rude lady named Wendy who didnt even try to help she, let us hold fot the manager for 20min and never came back to us. This upgrade is a **** dont you ever take it DSTV will make you suffer for their promotion. I am so disappointed. Why lie to people that there is no additional cost and now you ask us to pay. Pathetic service. I called three times using my hard earned money for almost an hour.
