EBK and auto dealers and auto trader are very good at not servicing they clients

Purchased a vehicle after one day of driving oil starts leaking all over the engine ,car keeps stalling doesn't idle ,drove it for 5 hour and all the issues occurred,the face is that I drove for less then a day and the issues occurred tried getting help from IDA but looks like those guys can't help or do anything ,yet they are the ombudsman for vehicle. EBK auto dealers are selling **** that looks nice and everything is tampered with don't go there and it's look reputable because it goes through auto trader website ,so you believe you are dealing with reputable people but IRFAAN the owner said he would change the oil cap after I mentioned taking it further he said don't even do that .and leave yet I was making payment the day before and the next day you chase ur client
