Bajaj Auto — Pulsar 220 / Unethical Behavior

Good Day,
Model : Pulsar 220 2014
The above vehicle which I surrendered for a service at JAIKRISHNAA AUTO PVT LTD, (185, 100feet road, Gandhipuram Coimbatore, Tamil Nadu- 641012), on 28/03/2022. After proper examination of the vehicle from the service advisor. He promised to do service on
1.Front suspension
2.Complete engine work except head
3.New Clutch plate
4.Brakes both front and back
5.Chain sprocket
6.Oil service and General services.
7.Rear suspension
8.Parking lamps in front head
And I suggested replacing the rusted nuts and bolts. And the advisor estimated Rs. 20, 000/- for the above-mentioned service and It took almost 4 days to collect the vehicle back from the service center and I have paid Rs. 18, 800/- on 31/03/2022. And the very next day I migrated from my home town (Coimbatore) to Bangalore for my work with my bike. And once I reached Bangalore I called the service advisor regarding brake issue and he said he will arrange a local advisor form Bajaj to sort out the issue. And no one addressed me regarding this issue.
After a month I have started to face the problems which I couldn't able to drive my bike to the office. After my personal examine I could find several problems in my bike such as Brake issue, drive train issue, wheel alignment, Gear tightening, Chain sprocket coupling is almost broken due to improper alignment, and chain sprocket head cover bolt was not fitted at the bottom and head nut was loose which is vibrating while driving, Rusted nuts and bolts are not changed and engine oil smells really bad when engine is started. After this issue I have contacted the service advisor and explained. He replied again, like he will assign the local advisor from Bangalore.
Even after spending the whole sum amount to the service provider, failed to do the work properly. Which shows the failure of customer satisfaction and I'm really disappointed with this service provider. However, this issue is truly from dealer side and Because of this issue even though I have my own bike but still I’m continuing with my regular travel in local transports. And I have clearly explained about my migration to the service advisor. He failed his promise which was totally unfair.
And also I have contacted the costumer care service via mail and to the authorized dealer thru call, but I haven’t received any kind of action taken from their end.
And as a final I have reached out to you regarding this issue and seeking for the better solution.
