Overall Bad Service; From Pricing to Delivery

I bought a TV from Dion Wired online, the advertised price on the item and catalogues was R8 799.99, however, they charged me R8 999.99. I proceeded with the payment as it was Black Friday and thought that I would raise the matter with them later and arrange for the refund of R200. This I have tried to do, through their social media (Twitter) team; whom promised me that a consultant will contact me and rectify the error. This has not happened, despite a clear violation of the Consumer Protection Act: you charge what you advertise. Furthermore, despite immediately sending ID copies for the TV licence requirements, acknowledgement of receipt came only after 5 days and re-sending the documents. To this day (11 days later), there is no contact or delivery from them. Dion Wired must improve their online service. In store, things go smoothly, they have some of the best sales people who know their products and are very friendly and helpful. I just wish they could transfer the same service to the online sales team.
