Tvs Motor Company — Faulty actions took place at service stations

Address:

Pune, Maharashtra, 411062

It was my third free service of my new apache rtr 180 abs, as usual I submitted bike for service to saibaba tvs, Chinchwad, pune.
Overall services were good but one faulty actions they have done with my bike,
They have tempered and removed both the original stickers from side covers namely "TVS racing", this I noticed next day of service.
When they called me for review I told about it but no actions from service centre yet.
I don't understand for what reason authorised service center may conduct such act with their customers.
