Swapped my rim

I'm extremely frustrated with the poor care for customer's vehicles and bad attitude towards resolving issues caused by the workshop. On November 25th I booked my vehicle in for a service and upon collection, my vehicle had an additional 11km of unaccounted mileage, grease on my dash and to top it off my rim was buckled. It appears that the rim was swopped as all four of my vehicle's rims were balanced a week prior and the buckled rim had a different balance weight compared to the other 3. They agreed to repair the rim after much reluctance. Two days later and after driving with my spare rim which is a \biscuit"I collected the rim from Weiss Vw and to my disappointment it is still buckled. I drive a 2011 scirocco 2.0tsi ND 555 993. Please could someone assist me and provide the kind of service the VW brand build their reputation on? The shocking service & arrogance of staff leaves a lot to be desired. My contact number is ***"""
