FORCING ME TO PAY FOR FEES NOT LIABLE FOR

I took my laptop to Vodacom Meyerton for repairs. I interactcted with Leighton who is the consultant and he told me it would have to go to HP as they don't do repairs. I asked him if the were any quotation fees in case I do not agree with the quote and he told there are no charges. He received the quote and forwarded it to me and I told him I am not going to do it because its too expensive. Now I am being forced to pay R200 for assessment fees and R324 for shipment costs before I can get my laptop back. I escalated this matter to his manager Peter, who was rude and accused of lying saying that its my word against his employee, and surely I knew it was pricey to fix the laptop. I am not willing to pay an amount because I asked before the laptop was taken and then Peter makes me an offer that they will pay the shipment costs as though its my fault and that this is the last time they make that offer. I felt disrespected and the worst service ever received by being accused a **** and being spoken to as though I don't know my rights.
