disgusted in absa

I bought a car on 17 June and absa financed me for 180 000 .then 2 weeks later I cancelled the deal and logged the complaint with absa informing them the car was in an accident and to stop the deal.I took the car back on 11 July.absa then sent out the assessors to check and also the person thinks it was in an accident.. The car was then sent to AA for a body check and also have defects of a accident car but yet is Absa siding with the shady dealership and said they are looking for the prev owner to ask if the car was in an accident..lol have u ever heard such nonsense..I'm sitting without a car as the dealer has my deposit and the car..my daughter has not been in school sins 13 July cause I don have transport to drop her...she is in grade 2.I'm so ever sorry I took Absa finance. If there is any person at Absa senior management please I need help...
