Royal Enfield — service labour charges

Address:

S.R motors royal enfield Nagarbhavi, 560091

Dears,

I recently serviced my continental gt535 @s. R motors nagarbhavi bangalore. I had a problem in engine and at first they estimated it to 35k for repairs which shook me completely. Later the service was done and they said it was 22k i was little relieved and paid the bill however later they said they forgot to bill a component bought outside and billed manually instead of e bill to 7k so my total service cost ended up 29k. When i argued they said anyways it's less than estimated cost and you should be happy. Does that mean they jack up price?
Please find the attached bill where the labour bill doesnt tally at all and the first tally comes to 4k which is irrelevant.

I have raised concerns to re support but they are not reverting and taking action. Is this a new way re is trying to make money or the service centre / dealers trying too dint money damaging re reputation? I would be more than happy if someone could help me

Regards
Rakshith
