Uber India — no response from uber

I am saikiran with mobile no [protected]. I took a ride in uber on05/05/2016. When i booked a cab i used payment method as paytm i was not using uber for long time after a year when i start using i got to that i have over due of 385.40 because of which i was unable to book a cab. By mistake i made a payment of 385 using my debit card. Even after paying my due amount i don’t alow me to book a cab. I realized i have to make the payment using paytm. So i made a payment again for the same ride using paytm. I would like to have refund but no one is responding
