Hyundai Motor India — No or very slow response from service centre

I have handed over my Grand i10 to Hyundai lohia automobiles Guwahati on 29.08.22, from the very first day the response was not too good from their end. Firstly they said it will take maximum 8 days to complete the repairs but it's been 10 days and I have to call everytime and they just don't know how long it will take. Also now they don't respond to my calls also. Really very slow and pathetic service by Hyundai. I was planning to buy Creta but after this I will go somewhere else
