Booked a voler car (Ford figo) on 29-30 july 2017 (Blr-w-figo[protected]. First of all the car was in pretty bad shape. The music system did not work. The car was 75000km running, so the clutch plate was like gone forever. It started hurting my feet after 50km drive. Anyways while returning the car there was extra fuel for which i supposed to get refund (Almost 1/4 of the tank).
I was informed that i would be getting the refund in the next 5 working days, at least i would be getting a confirmation the amount of refund. I waited till 7th aug., when i didn't get any response from voler i called up the customer care. I came to know that the the refund is not even initiated. The executive who was handling the call informed that he will initiate the process right away, and i'll receive a confirmation from volercars.
But alas, nothing happened. Just to know status i again called up on 16th aug, and found out that though it was initiated, due to some technical glitch i did not received the amount and it will be credited to my account within 48hrs. Again, i called up on 21st aug, just to know the same thing, they did not even know how much the amount was to be paid and could not give any reason for the delay, just said that the amount will be credited within 48hrs. Once again i called up on 23rd aug., i was shocked to know that the refund was not initiated at all. The executive cannot even confirm the amount. I asked to sent me a mail with all the details (The refund amount & the date by when i would receive it). She confirmed that within 10mins i would be getting the mail and within 24hrs i would be receiving the amount.
But even today i did not receive the amount. I called up in the morning of 28th aug. Then i was again informed that due to some technical glitch i could not receive the amount. She could not provide any further clarifications. And also she confirmed that i would receive a mail with all the details within 15mins. But as usual i did not receive any mail.
When i realized that calling them was of no use i started sending them mails. But that too, to my surprise, was of no use. Even after sending 7 mails i did not get any concrete reply from regarding the refund amount or any commitment by when are they going to do the refund. I even warned them of taking legal actions, but it seems they don't care about that too.
Now after doing some research i find that it is the same case with many customers. People have waited more than 4 months to get the refund.
I have lost all hopes now. Not sure what to do. I don't know how to extract the money out of them.
