Guys, need some advice. Would like to check when actually is a wheel balancing and alignment needed. My car is just 1 year old and service centre asking me to do balancing and alignment. Or is it that while testing the car service guy hit a kerb or something?

So is it that the premium brands such as bmw, Merc, volvo service centre will do it every 10k or 20k and charge us for it if not covered under their free service package?
