Royal Enfield — Bike not getting serviced

Address:

Idukki (district) kattapana

I have submitted my bike Royal Enfield 350 classic (KL-37-E -4994)on December 26, 2021 for an accidental service. even after almost 3 months still I haven’t received my bike. I have already visited the service centre more than four times and they confirm the delivery within a week but never received
They created the service job card for the vehicle after two weeks of vehicle submission(on jan 7th 2022)
Even after all these visiting and asking for the delivery They have not even called me one time regarding the reason for the delay on delivery or the current status of the vehicle. The promised date of delivery has been crossed more than 4 times
