Ola Cabs / Ani Technologies — ola shuttle did not stop at pickup point and I am not getting money refund

Address:

Kolkata, West Bengal, 700029

I booked ola shuttle for travelling from Triangular Park to DLF1.Booking number SRN7255175. There is a traffic signal just before the pickup point. The shuttle waited in the signal for 30 seconds and did not stop at pick up point. When I called Ola customer care, they checked their system and told me the shuttle stopped. As the car stopped for red traffic signal, may be it was showing in their system that it stopped.
Rashbehari Avenue is one of the busiest roads in Kolkata and it is not possible to board a cab when it is waiting at traffic signal. That is why pickup points are there.
They did not check at which location the shuttle stopped and did not refund my money.
