Tvs Motor Company — Tvs iqube parts unavailable

I have purchased my iqube on November 2021, i recently met with an accident in December 2022 and i have given the vehicle in Bangalore dealership named THE BHARATH AUTOMOBILES which is the authorized service center for tvs bikes and mopeds, i was told that the chassis need to be changed and other damaged parts will be covered in insurance. its been 2months and despite the continuous follow ups with the dealerships every week, they are telling the chassis is getting delayed, still the chassis is yet to receive. This is unacceptable.
