Shoppersstop.com — Wrong product delivered and not refunding

I'm really surprised with shoppersstop policy,

I bought Ray-Ban sunglasses unisex, but delivered kids size(not returnable), I called customer care and logged a complaint with pics, after 2 weeks of follow up finally they arranged return and refund, return pickup is done and I don't know since last 7 days it is still in transit, sometime it shows pune, chennai & Bangalore as destination.

Refund will be done after reaching the warehouse & quality check which takes 10-15days. Then refund will take 5-7days to reflect in my account.. this is insane.

Not for customer mistake shoppersstop locked my money and simply saying as soon as possible every time I call.

Please refund my money
