It has almost been another week and still no answer from We Buy cars- my calls are being ignored and I have requested to speak to Ruan at the dome multiple times. Worst of all when I tried to follow up on registration this morning they had the wrong vehicle listed under my details. This raises huge concerns - firstly unroadworthy vehicle sold to me after I was told it is and now wrong details and still no answer on registration.
