Very disappointed

i am very disappointed yesterday i went midcity auto body at 470 madiba street, arcadia who are your authorized auto body repairer. To collect my car which was booked last week for a scretchs on my right door, the kind of treatment i received was horrible to a point that when i left the guy who was assisting me told me to never come back even my friend my never come by the name of sergio. The problem began when i was making my payments, i first made a payment from my fleet card which declined they called absa for authorization it was resolved. Then my nedbank card also declined when i was making the rest of the payment, the lady called standard bank for authorization but paid with a transaction on the phone instate and now could not bank on their system, that's why i had to go through the humanilation. I got there at 14:50 and left at around 17:48. I called nedbank the first they didn't even help. Immediately she called made that transaction it went of my account i received, because they didn't have proof i was now treated like a criminal. I was rudely told that i must that if the payment does not reflect i am not going to get my car and made it as if the fault was on my site. I kept telling them that the fault was with their system, until one of them who was trying to help tried a transaction with the card to discover the problem was with their swiping machine i have never received such bad treatment before, i was never given a change to even check my car before driving off. Being in the financial services industry myself this was not is really bad.
