VW Golf AC not blowing cold – anyone tried this Sharjah shop?

I’ve got a 2018 VW Golf and the AC is barely keeping up with the heat lately, probably needs a re-gas or maybe the compressor is acting up. I was searching around and landed on https://caracrepairsharjah.ae/brands/volkswagen/ but there’s barely any info or customer reviews on the page, so I’m hesitant to just show up. Has anyone here actually taken their Volkswagen to this place for AC work and can tell me if they’re honest about diagnosing issues like a leaking evaporator or a faulty pressure switch? I don’t want to drive all the way from Dubai only to find out they’re just a tire shop or something. Appreciate any real experiences before I waste a morning.
