Warranty cannot be used for Samsung Tablet

I had purchased a Samsung Galaxy Tab 2 from TAKEALOT in November 2013. The device is still under warranty until November 2015.<br> Recently, the tablet has been crashing so I took it to Samsung for a software upgrade which is covered by the warranty. Samsung however cannot help because the invoice I received from TAKEALOT does not show the device's IMEI number which is used to link the invoice to the device.<br> <br> TAKEALOT could not alter the invoice or write an official letter to state that I purchased the device from them as they do not have a record of the IMEI in any of their documentation.<br> <br> As the customer, I now cannot use the warranty because TAKEALOT did not put an important piece of information on their invoice. It therefore might be better that consumers purchase electronic devices from physical stores to ensure that the warranty can be used (which we pay for).
