I had purchased Aerocot inhaler along with some other medicines. The inhaler they supplied is of old stock expiring much earlier. However they have billed for fresh stock with higher price. When the matter was raised and asked for a refund, they informed that I can exchange it at their store of supply for which I have to spend more than the cost of the medicine. Now I have stopped buying from them and use Flipkart. Iam very happy with their price, quality and delivery experience.
