I pallavi shah having the ph no [protected] had a coupon chn49 which should give 7 kmts at 49/. And after that rs6/km i travelled from baliah avenue to walltax road at 3.50pm distance of11.5 kmts and 41 mnts driver name sobanbabu j. On 17th december i had asked for mini but was upgraded to sedan and i had to pay 214/ where as it should not be more than 49+30+41=120/ i had received the message that i have been upgraded or i would not have taken the ride. I request you to give me the refund in ola money which i can use in future.
