Worse service and sworn at by owner and son

I took my bike to Perry Bikes on the 19th February 2018 for a oil and filter change, I rode the bike from my home to Perrys no problem just needed to boost the battery. I called on the 21st to see how they where doing and said the will finish soon just have a starting problem, later that day I received a call that the service was done but the bike does not want to start it has a service light problem that say there was a wiring problem. I said no problem just fix it because there was no problem when I took it in. a week later they used that there is one mechanic. On the 23th I call Vernon Perry owner and ask for his assistance he said he will look in to it and get back to me, he called me later the day and said the wiring is a mess and he will send it to Hillcrest branch the have a very good mechanic there, all looked up again he also said they will call me with feed back that happened on the Tuesday the Thursday I call and they said they did not start yet now the 8th Feb,Monday the the 12th we where at the shop because we have a registration problem with an bike they sold us 2 weeks ago, I saw the owner and said he will ask what is happening with my bike and short after when we came down he said they will start today and I will have it back on Wednesday. Today I got a call it is back at Durban North I must pick it up, because it is a mess. I took a drive there to talk to them when I got therwenyte I spoke to the service manager, that showed me the report that said the full wiring harness needs to be replace, battery almost flat after standing for almost 4 week, the Ecu looks like it burnt and sorry they not prepared to work on the bike any more because it is a peace of S.... there word. I told Vernon Perry and his son that it does not make scene how I drive a bike in and when it comes out it has more that R 40 000 damage according to them. I showed them point after point where they wrong and staff that did not do there work and Vernon just said but that is not his problem, by now his son is swearing at me and told me what a S... bike this was and it is irreparable and then I said but I rode it in to the shop and they saw me. His son just went on swearing to me when I said to him is this how they treat there client he did not care. They just wanted me to take it in pieces like they worked on it to my home now. This is the worse service and I have never been sworn at by a owner ever. Now they want to put it together and dump it at my place.
