This is regarding the online order of crocs women shoes which i ordered on 16july2016 and it was delivered to me on 20july2016.
Unfortunately the size was big for my feet. I had contacted their customer care email asking for exchange of the product with a smaller size of the same design.
They didn't responded to my email.
I also called their customer care number several times (More than 10 times in a day) but none of them were picked up by their operator.
