Shocking, uncaring service! Don't buy a Haval!

My Haval Jolion experienced major problems with 'turbo lag'. After my first visit to their Williams Hunt dealer in PE, they just said there was no problem and I must have been inadvertently driving in Manual. How lazy, sloppy & unprofessional. So of course ended up back there and they then did discover a problem with the turbo activator. For over a month now they have been awaiting a part; there is no proactive communication from them, I do all the follow ups. I emailed GWM's customer care; they promised a response within a day; after 3 days and after I have followed up, finally a lazy response looking for unnecessary info instead of them contacting the dealer. Still no response from my reply. Over a month later and we still await information about when the part might arrive.
