There was an issue with the size for which I had to raise the exchange request. It was very well handled with timely updates. However I would like to suggest that if the exchange process is updated like the item to be exchanged is picked up along with the delivery of the exchanged item. It will save the long wait which is there currently where the item to be exchanged is first picked up, then it has to reach the warehouse post which the new item is shipped and then delivered.
