Delayed maintanance

Me & my partner bought a car from Auto pedigree Midrand on December 15 2021 and January the 14 was called back to be fixed a water leakage and it was brought back to me the next day on the 15 january 2022. I told them the boot was not closing and they have dented the boot and made it worse than it was. They took it back on the 16 january 2022. Remember, this is a business car and it is now unavailable for days, today is the 24th of january, we have lost clients due to incovinience and also out of business because these guys are always saying tomortow it will be done, tomorrow it will be done and now marks the second week...We pay the car by tge money it makes,its almost month end we dont have enough funds to pay the of i did mention to them that it must be a priority to them and begged them. I need the car before this weekend to go to the Eastern cape, please i need assistance on these people.
