Bidvest bad management

About a month ago I had my vehicle wrapped with a white wrap coming from the company Kolok in Gold reef road Gauteng. I spoke to the manager Mr Mogamed on a couple occasions seeing that the person who did the wrap totally messed my vehicle up. Two weeks after the wrap was done, I had to redo the wrap seeing that the wrap that was supp**** was of very bad quality and did not stick to the vehicle. The gentleman that did the second wrap also confirmed that there was something wrong with the wrap seeing that it comes of like paper. Kolok did not have more white and suggested we go for another color. The gentleman that did my second wrap confirmed with me that he had the same problem with the product from Kolok with a previous customer and that the product is inferior and does not stick to the vehicle. I discussed this matter with Mr Mogamed and a lady by the name of Yolande that works for Kolok. I demanded a refund from them for the first wrap material seeing that there was something wrong with the material. I was told that they have to send a sample to France to have it tested in the laboratory before they can repay me but that they will look after me. Three weeks ago I was told by Yolande that they will reimburse me within the next week. I was never reimbursed and if I try to get hold of either Mr Mogamed or Yolande, they just ignore me. They read and open my messages but refuse to reply or phone back. Please be careful of this company for you will get a bad product and you will not be repaid for your loss. It is a shame that the Bidvest group have a division with in the group that treats customers like this. This is so bad for the Group and I do hope they can change this around.
