Webuycars disaster!!

I have never been so poorly treated in my life trying to buy a bakkie with my family. Me and my family went to "webuycars" today to buy a bakkie that we desperately needed and sould have been a great day for us.we arrived at their shop and we explained that we would like to buy a bakkie for the family and was taken to one of the exits where the cars were standing outside. At that moment it started dripping a light rain. The " salesman" said to us to go and look around outside for a bakkie and if we find something to come in and find him as he is not going out in the rain. We found a bakkie that we liked and found the salesman to help us. After standing outside for almost an hour they aventualy found the keys to the bakkie and we could go on a test drive. Started the paperwork for the sale and was asked for a bank statement that I provided. Halfway through the process the salesman informed me that the bakkie is not the price that was advertised on the vehicle and that we now had to pay and extra almost R80 000 more for it. My mother made a joke saying that is the increase on the price because they have seen the bank statement? The salesman jumped up and stormed of the speak to some of his colleagues standing around and thatcis when we realized he was serious. I walked up to them and asked what is the problem as we are paying cash and need to conclude the deal as we have a lot to do before the end of the day. I was told to wait at the table he will be with me shortly. He returned about 10min later with the branch manager and was told the price is not correct on the bakkie and had to pay R80 000 more. I said why sould I pay R80 000 more on the it as the price was on the bakkie. The manager told me that I sould use my eyes and read the description of the bakkie and that it is not the same. I tried to explain that why sould I read the description on the price if I see the bakkie in front of me and that we only look at the price. I told he that the price was on the bakkie and I would like to pay the price advertised on it and go. I was told it I can not read it is not there problem and that they refuse to sell the bakkie to me as they have that right and asked us to leave. What sould have been a fun and happy day for us turned out to be a day from hell. We felt so umiliated as the place was full of people and as we walked out the staff was congratulating each other and smiling. We are disgusted with this experience.
