Delhi Transport Corporation [DTC] — Refund regarding E bus pass

Respected Sir/Ma'am, I wanted to tell you that On 6 th September I applied for e pass through dtc website and I paid 400 rs but next day when I checked the application status it shows that the application has been rejected but the amount that I have paid is not refunded. I registered a complaint on pgms Delhi and on 14 sept I got a respond that my payment will be refunded to that account from which it was deducted but no date was given 10 days passed, no refund came. I want a refund as my application rejected. I request for a refund as soon as possible.
