Ola Electric — No Committed Scooter delivery, No reply to mail

I purchased Ola electric scooter Ola S1 Pro in the month of February, 2022 with full and final payment. Suddenly, at the time of delivery, company is saying that price of scooter is something else and not on what I booked. Have mail communications with customer care of the company.

I asked them to either deliver my scooter or refund my money with interest. They are not reverting to the mail.
