Had a cracked ws. Send to TS Ipoh to change last week. Got my car back on Thursday. 2 days later after my siesta, saw my new ws had cracked by itself. Went to TS today and was told it was an impact crack! What nonsense when it had cracked whilst parked in the porch. My complaint was dismissed outright by the service advisor and a mechanic. Now they are forensic experts too! What to do next?
