Delivered incorrect product & no stock

I have used [URL Removed] on a number of occasions in the past and never had an issue. However after stumbling across an \unboxed deal\" on the Go Pro hero 4 Hero silver edition I ordered it and waited the 5 days it took to come from Cape Town. Upon receiving my order and then opening the box I found a Go Pro Hero 3+ which is vastly different from what I had ordered and none of the cables or other accessories were included either. I subsequently phoned the returns department to have the matter sorted out and for them to deliver the correct purchased product, however I was told that there was no stock available in the \"unboxed deals\" so I would either have to wait for the deal to come up again or get a refund after an investigation of what went wrong (they couldn't tell me how long this could take) or something that really surprised me was that they could apparently repair it (from a 3+ to a 4) which just showed me they had no idea what they were talking about when dealing with this complaint. After a long discussion I asked them if they could just please send me the normal GoPro 4 deal (where I would pay in the difference) but apparently they cannot do that either."
