Incredible Swindle?

I purchased a dell computer from Incredible Connection Cavendish ( IC) with the understanding that should anything go wrong the matter would be attended to at my office/home and that there was a fully repairing or replacement guarantee. The HDMI port is faulty, Dell international were proactive and happy to replace, but IC again dragging their feet. First were unable (or unwilling) to provide a legible copy of the receipt (the very faded one was not first choice of Dell Int, but once they realised how unlikely getting anything from their local supplier was they processed the claim without this). Not IC note that the computer model is no longer available, and that i have to pay IN another R3000, plus bring the laptop to the store. Oh, and any rebuild or save and restore of information and configuration is for my account. I spent R16,000 on what was intended to be a functional computer - i require the same. IC are not responding to any emails.
