Bad Customer Service When Ordering a Crucial Part

Our bakkie got broken into at a garage in Midrand on the 1st of October. Then we went to Nissan Menlyn, paid for a lock (because it needs to be ordered from overseas) and our waiting time was suppose to be 2 weeks max. So, everyone know by know that the parcels do take longer now and that is fine so we budgeted on 4 weeks I phoned about the 19th but then the part was not there yet. Then last week about Tuesday on the 27th Jason phoned me and told me that Nissan overseas did send them a part but that was the whole lock system and not just the little part that I ordered. He told me that they are very sorry but this system is about R3 500 and not the R800 that I paid so, I don't have to worry he is going to place a new emergency order for the right part and it will be here by the 4th of November (so that is already 1 month later). Today when I phoned him he said no, the new part will only be here on the 16th of November. I explained to him again that we are currently driving with a bakkie that can't lock and if it get ****** the insurance will give us nothing. His response, well that is your choice. As if we have a choice... Our "choice" was to wait for a part for 2 weeks not 7 weeks. I told him that good customer service will be to put the part they have in the bakkie but he said they will not take the loss then I will have to pay more. I told him if it is my business I take the loss because then I will surely get a new customer or 5. This make me furious, first we live in a country where *****s can break into your vehicle just when they want to with a security guard that watch, then the only place where you can buy the part will not deliver good customer service. They made the fault, the company overseas send them the "wrong" part, so they were suppose to fight with that company. Now, I have to fight with them because they will not put that part in my bakkie. I just have to wait a month more than what was agreed on. I can do nothing because surely they will not give my money back as that part was especially ordered for my bakkie and even if they give my money back I will have to go through the whole process again. BAD BAD BAD CUSTOMER SERVICE!!! My bakkie can get ******, and then I will have nothing but whatever ... they feel nothing.
