Tata Motors — key misplaced by malwa service centre.

Address:

New Delhi, Delhi, 110033

I had given tata harrier for service on 14th march, 2020 to malwa tata service center, jahangirpuri industrial area, 110033.
On reaching home after taking car back from the service centre i found that emergency key was missing from my key set.
On informing the service centre, they are clueless about the key.
This is a highly unprofessional and careless behaviour on part of service centre, previously also i has faced lots of issues with this service centre.

This is possible that the key has been stolen by someone with some malicious intentions. The key can be used to steal the car also.
I haven't got any assurance from the service centre about the replacement of the key. I want that my whole key for tata harrier is replaced and not just the emergency key free of cost.
