Jabong.com — wrong size send

I have ordered a jeans from shoppertree for my son size 9-10 years but when i received my order i t was wrong size product 4-5 years and when files for return there comes a error in return initiation - tried multiple times. My order no is [protected]. Please solve the issue and refund the amount

I have very bitter experience with jabong. They even can't reply for the return. Every time i tried for return there comes a line - error in return initiation. On the other hand in myntra they are very good for their return, they pick up product from our address, refund the amount within 1 week
