Nowhere. If the bicycle was serviced two months ago, quite from the passage of time, it'd be impossible to prove anything, even if you have an in depth knowledge of the hub/servicing techniques/work undertaken etc, etcArb66 wrote: ↑31 Jan 2025, 9:35pm Had my hardtail serviced start of December changed back wheel bearings strip & regresse.had to go back in today 31/01/25 has back axle has snapped cassette is wobbling which they put down to aggressive riding something about riding on loose cones(there sealed press fit bearings?)I personally think it’s shoddy workmanship & they haven’t over torqued to correct spec.where do I stand….
And honestly, the cost in £'s and time in trying to prove anything, wouldn't be worth it.

It's perfectly possible to buy an entire, basic wheel for peanuts online, an entire basic wheel, often a similar cost to 1-2 Hr's of paid labour
