Laptop repair

Took my laptop to Huge PC Computer Distributors in Centurion to be fixed. The quote was just a little over R6000.00. You have to pay the full amount up front before they will fix your device and then it takes 4 to 6 weeks before you get it back. Went to the bank to draw the cash and went to pay. Asked if I could get any discount. Lol. Comoany policy---NO!!!! DISCOUNT FOR CASH. Could anyone recommend an ethical computer company in Pretoria should I need to take my laptop in for servicing or repairs in the future
