Ola — misleading information about leasing

Address:

Ola head office, vimannagar, Pune, Pune, Maharashtra

I had applied for a car on a leasing basis in ola office located in pimple saudagar, pune to their sales executive shubham sooryavanshi. After reapetedly asking them that have they provided me all the proper information and after them assuring me that they have i paid them 15000 rupees for booking datsun go car on a leasing basis. But during our training they told me that mi phones and as well as oppo, vivo and apple phones won't work with the ola app. Now i have a mi phone and i can't afford a new mobile which will be compatible with the ola app. Since this information was withheld from me i am demanding the full refund as they had promised but no cognizance has been taken from their part. Please help me with this problem.
