Tata Motors — IRA not Activated

Address: Mahishbathan, coochbehar

I have bought TATA Safari XZ+ in April, 2021. My IRA application isn't activated till today. The showroom workers had taken my KYC(s) and also registered the same. I had provided them the OTP that came to my mobile number @ [protected]. Thereafter whensoever I try to register in the said application it says that my mobile number isn't registered. I have calling the customer care for about a week but they are not receiving calls. Once they received the call and assured me in calling back within 24 hours. But many 24 hours have passed but no call is coming till date.
