Bajaj Auto — NSM Bajaj Pondicherry - Damage to vehicle, Unexplained bill charges

Address:

NSM Bajaj, MG Road, Muthialpet

I handed over my bike for service in Jan. There was no response from them for more than a week. After dropping in at their office again, I was told over phone that replacement of parts would cost 3650. At no point was there any mention of other major charges.
1. When I went to pick up my vehicle - bill was charged at 11, 000.
2. There was a dent on the vehicle.
3. The date of vehicle handover was changed on the job card to a week later. When asked about this, the staff said they will change it to whatever date is convenient for us!
4. The RC is in my name but the bill was issued under my vehicle number, but in the name of someone else.
5. There was an unexplained "Outside Labour" charge of around 5000, for which
5A. No breakup or explanation was given about what service was done outside.
5B. No permission was taken from me before handing over vehicle outside.
6. I contacted Aakash Bajaj - the local office and the ASM in Chennai - both of whom have still not offered a resolution.
