Worse car sale ever

purchase a VW polo model 2013 on 13 October 2021 from we buy cars in Springfield, Took the car to VW Durban for trade in to buy another car .they took a print out the service history and found out that service in 2021 July mileage was 195866 km and now car is showing 175000lm how is that? . We was shocked cause when we purchased the car mileage was 131000km and we buy cars did a service in 2021 before we can take the from them and charged us for the service and parts that they repair, we ar so angry this is a big company and they give u DECA report so this is not a code A car it is code B, we already did paperwork for a new car with VW now this is prolonging the process , This is ***** even we gave the mileage what we bought the car with to the insurance company,. They need to reimburse us for all we did in that car ,if we new about the mileage being so high we shouldn't of purchase the car the exact mileage now over 220000km but it is saying 175000. This matter need to be sort out urgently cause we already did a deal with VW so this car need to be sorted so we can buy the othe car ,please any one who buy from we buy cars go get a service history of the car when u buy . Wil rate the a 0000 , cause this is ***** don't no how the bank approved this purchase , but thanks for vw In Durban for taking out the print of the service and they say they can't except the car as a trade in .
