Dishonest until the end on a revision on a Twingo: invoicing of a cabin filter when the Twingo has not equipped it and overcharging of all the elements compared to the online quote. I am promised a refund in 2-3 weeks (91 in total anyway) and 1.5 months later I still haven't received anything !! Avoid at all costs !!
