Mahindra And Mahindra — VVC motors complain on car service

I gave my XUV500 car (AP09cu3891) for service on 29/Sep/2021 in VVC motors Hitech City, Madhapur, hyderabad. while taking car back found key got damaged. Unlock button not working and when i asked advisor or manager they are telling like it was damaged before. Button damaged such a way that i can't even unload my car, need to press too hard and with nail. if this was the situation before then i am sure advisor will notice and report to me or during the service for 2 days he will inform me. but nothing happened. Please check this issue and do the needful as now they are asking me to pay replacement key charges which is unfair.
