Meanwhile, I came to know about several complaints on this online shopping site in several complaint forums. I contacted the customer care and they promptly registered and sent a mail and then I got a mail from business executive saying that the product is much in demand and they need another 7-8 business days for delivery. I contacted once again after a week and this time my mail to a contact mail ID resulted in automated reply to file complaint through their website, in which I did not register while ordering the tablet. After some attempts with customer care, finally I got the item.
The above experience taught me a lesson to search for complaints on the site which we want to use in internet, so that we can take an informed decision.
There is a website www.akosha.com in which one can file their complaint against the companies. Depending upon the work, they do for free or charge some amount. The representatives will try to resolve the issue and if not possible at the end, they help the aggrieved to file complaint in local consumer forum.
