Worst place to buy from!

I bought a bike from We Buy Cars Silver Lakes a week ago and had them transfer it to their Johannesburg branch at the dome for me to collect last Friday. I specifically asked if it is a reliable running engine, roadworthy and all lights working which they confirmed... When I arrived it took them an hour to find the bike and when I saw it for the first time it was clearly in an accident since both mirrors were shattered, both front indicators were missing, bike was leaking oil, engine died when throttling, gear shifter was bent and unusable, broken front wheel cover etc. When I asked the sales guy why he didn't inform me the bike was in an accident he simply said he didn't see anything wrong with it. I told him last week friday 10am to cancel the deal and refund me ASAP. He said he would do and I'll receive my monies on Monday morning. When I followed up on Monday morning they told me they don't d cancellations over weekend so the deal is only being cancelled then and I would have to wait up to 3 days for my refund to be received. When I followed up this morning multiple times the customer sales representative is unavailable and I was told she would phone me before 9am. When I phoned again at 10 she was still unavailable so I asked to speak to the branch manager who I was told i also unavailable and would call me back. A lady eventually checked my ticket number and said that there is a comment made by the customer sales representative that the cancellation was only done Tuesday and that I would have to wait another day. This is now the 3rd delay and I just get told to keep waiting an extra day every time I ask for an update. Nobody is calling me back, nobody is responding to my emails, nobody can tell me when my refund will be received and they simply just don't give a ****! It is now 12 and I have still not received any call back from the Customer Service representative nor the branch manager who are both still unavailable. My one friend was also sold a broken car by WBC and is now forced to get Ombudsman and lawyers involved as they simply ignoring his calls, emails and follow up as well which is the worst possible after sales ever! I strongly recommend against buying anything from any WBC.
