Hidesign India — Return and refund of purchase

Address:

Mumbai City, Maharashtra

I had bought a bag online from Hidesign website on 21st Dec (MAO 01 BACKPACK, Cost ₹10, 445, Order HD100504)
I recd the same on 27th Dec. However, I found the same t9 be small, and sent a mail on 27th Dec at 8.10 pm asking for return and refund of the amount ticket no 6905). However, there has been no response since then, despite reminders sent on 28th Dec at 8.48 pm and 29th Dec at 7.38 pm, and calls to the customer service no[protected] on 29th Dec at 11.10 am and 30th Dec at 9.45 am and 12.31 am. But there is no response on the number.
This is pathetic service.
