We had booked car under MICRO. However OLA on its own upgraded to MINI and levied extra charges of Rs. 76.80 + Service Tax @ 15%.
We need Refund of Excess Charges levied alongwith Service Tax, since we booked for MICRO and WE DID NOT REQUESTED FOR MINI. OLA had SENT ON THEIR OWN.
Why should we bear the Extra Charges.
