Bad attitude and dishonesty of owners

I had a very bad experience with the owners Shaun and Melanie Pretoruis of Postnet Hoedspruit. I did some printing work and paid 4 times the same price. On the 5ht time they charge me about 4 times the previous price. I at first thought it was a April's fools joke but the staff insure me it was correct. I contact Melanie and she said it is correct. I told her that I am not prepared to pay such a insane price. She then told me that I can go somewhere else and she will through the work done in the dustbin. My partner decided we need it and he was prepared to pay the insane price, but they show him away and told him they don't have the work done anymore. I realized that Melanie can do what she want because they got the monopoly here in Hoedspruit. Shaun and Melanie Pretoruis also open a Postnet brach in Nelspruit now. Be very careful to do business with them.
