When you look for some offer and buy the item, in Billing original amount will be billed instead of offer amount.
If you are not careful, you will end up loosing in money. when you approach customer care, which is worst care. they will simply say sorry, and convey message saying it dept not updated prices.
After complaints also, they wont update, even next day same billing mistake you can find out. Just cheating customers . when you buy lot of things with trust, you really wont have time or big bill you cant verify so carefully. this weakness of customers they are en-cashing.
So next time, please be care while buying offer items.
