Pick n Pay Preller Square Bloemfontein SHOCKING!!!

We went into Pick n Pay Preller Square to order Artappel and Wortel slaai for 30 people. They told me it is R500 but they will make sure. I order the above and went to fetch it 2 days later. They put my order in plastic buckets. I don't know if this buckets was clean beforehand. I was very disgusted because this order was for a braai for my clients. I ask them if they could put it in something else and so they did. I ask what the price was and they said they will weight the order. They did not paste the weight on the plastic. Secondly they said I must pay another R200 in. Now the cost is R700. I was shocked!! The portions was so small I could not believe the price. I paid the R200 in and drive off. The manager of Pick n Pay phoned me and said he check the order and there is discount for me. I ask how much? He did not know yet but he will phone me. I wait the next day untill 10h30 and I phone him. He was suppose to phone me. He said the discount is R100. I still don't no what the weifgt was or the order. I was shocked. People who see the order told me they pick n Pay Preller Square are ripping me off!!! I also thought so!!
