I recd. the COD packet through airway bill no. [protected] on 16/02/11 and paid Rs.1700/- including the delivery charges of Rs.50/- I called the customer care immediately and informed them that the printout is not clear and that girl told me that it would take 24hrs for us to activate and then if any complaint I can call her later. I called pizzcorner on 20/2/11 to place an order they told me that my vouchers are not activated.
