The reverse pickup was done by shadowfax but the refund is not yet processed. I have written numerous mails and tried reaching on all possible customer care numbers. Not a single number was picked up and no response to the email.

I have attached the reverse pickup slip as a proof of return. Please process my refund as soon as possible.
