Told it needs a service but actually the turbo history.

They hid the fact that the turbo is completely broken, now I am getting the run around to return the car. The Dekro report said it drove well, no mention of the turbo being history. The salesman said alk it needed was a service. The turbo is non function completely and needs to be replaced. At the agent a new alone cost 80 k or an aftermarket one at 35 k I have already spent 16.5 k on repairs to the cv joints and shock as the Dekro report mentioned with no mention of the faulty turbo. Customer service are pushing me from pillar to post in wanting to return the car. Telling me to contact the salesman who just sent me a little image of how he raised a concern and the customer service will contact me which has fallen flat. Sadly only now the this happened, so people have said, " but you should never have bought a car from We Buy Cars"
