Uber India — non arrival of vehicles on 28/10/18

Address:

600128

I booked uber cab on 28/10/18 from the bus top (Towards guindy) opposite to alandur metro station. The first cab driver cancelled the trip as soon as i told him my destination the second driver never bothered to answer my call and he too never reported. Both trips carried a regret note later.
Today i booked a cab to adambakkam. The arrival time was 14 minutes and i had to do a second booking only to note the fares was hiked by 30%.
