engine replacement

Very bad service MD disrespects the customers. I cannot and will not recommend this dealership. Very bad workmanship from the workshop. I had my veh engine replaced because of a runaway and they give me a new engine that's also had a runaway. Now they insist I must take it like that, what about the long-term damage it might have caused and now making it my problem. R170 000.00 cost to date.
