Took my car in for repairs on the 19th Feb, they keep postponing dates I haven’t recieved my car back. I have to be tho one contacting them each time they don’t keep me updated. I have even asked for my car back I’ll see another plan they keep sending me from pillar to post I’m not even sure if my car is still safe with them 😕 yesterday they told me to fetch the car today at 4pm, now they are saying there’s no one to talk to regarding my car because they are all busy at work shop. The last person spoken to on the phone was Poaline
