Poorest service on the continent

I purchased a vehicle from Webuycars Silverlakes and since I collected the car it has given me problems, now I have to run around to have it fixed the sales person doesn't communicate with me and I don't know where I stand or when I am going to get my vehicle back, they said a manager would call me it's been over a month and I still haven't heard anything this has been the most disgusting service I've ever received I mean I'm paying for this car I didn't get it for free.

I'm looking for someone to assist me urgently
