Limeroad — wants to cancel my order

I ordered four items in womens clothings but changed my mind quickly. I needed to cancel them because i felt charges were too high and it took the total price way out of my budget. The app is crap without this option. Please provide option for cancellations. Also if we buy anything using cash on delivery, limeroad does not give cash back. Instead they give LR credits using which we can buy something else on their site. What if we dont want to buy anything again on their site? First we cant cancel order and then their return policy is not COD friendly. Please do look into the matter and do the needful.Thank you.
