Robbing people of their money

Goodday my Audi S4 had a Gearbox problem not selecting the gears correctly but still drives it was taken into Mayfair Gearbox repair centre in Shelby the Quote on the repairs was sent to us stating that it would cost R84K to repair I than got someone else that said it could be repaired for between R40K and R45K we then agreed on the other party for R40K as it was half the price we then informed Mayfair that the vehicle would be collected the following day they then all of a sudden changed their minds and said that they can repair it for R45K this is day light ******* so in fact their original Quote was double the price its a disgrace I will never recommend them and they will never see me again it's robbing people from their money
