Bad service from Hollard

I took my car 3 years back for pullies and they fixed them immediately and approved the same day. And this year last week I needed my pullies to be changed again. And even as of today I have not received feedback.the workshop is contacting them daily I also do email and calls not getting feedback. It's now Christmas I'm was planning holiday what will happen if I stuck with kids in the car.if i ask them what if I pay and they reimburse me later still no respond. NELSON dealinh with my claim. He requested fill service history from 2015 and was given even waybavk from 2012. Their ride.stay away. If one has policy please run fast to competitors
