Royal Enfield — bad customer service. overcharged and took 50 days to repair incomplete

Address:

Nibm, 411060

Dear sir,
This is regarding a royal enfield (Blue colour)
Dl4s ak 8164
Was given for repairs for gear box issues on 19 jan 2020 at platinum motors service center fatima nagar.
The bike has finally been given after repairs on 7 march 2020.
Though was supposed to be delivered by 24 jan 2020
It is very disappointment to see how platinum motors service center is mismanaged with no consideration for customer service, ignorant and rude behaviour.
The repair work and part changes on delivery were incomplete
Work required to be done
1 gear box issue
2 fuel knob replacement
3 foot rest replacement
4 brake light replacement.

1) the service advisor (Prashant) didn't bother to reply to call and messages.
2) the billing system incharge (Akshay) said not possible to give bill but asked to make payments.
3) he service manager is too busy to get the work done and is only good at pacifying than actually getting work done
4) bike repair work of only gear box and fuel know carried out. Rest all the jobs not done stating no spare available even though bike was in workshop for 50 days.
5) bill amount told 6100 when bill given 8500. No previous estimate given till day of delivery.
Very mismanaged workshop with very disappointing customer service is this how a brand like royal enfield maintains it's name or brand.
I hope this is seriously looked into than just another email.
