Levis — Refund of the jeans I returned

Website:

www.levi.in

Hello my name is Zainab Bano.
Order number IND[protected].
I ordered a pair of jeans from levis website but had to return it due to size issues. The return was picked the next day. The delivery boy said I will get a mail for the refund to give bank account details. No mail came so I mailed them instead. They asked for my bank details. I gave. But nothing happened after that. I am waiting everyday for my refund but it is not getting processed. Please help.
