Unable to use Warrantee on Samsung S4

Purchased a Samsung S4 in October 2013 and took it into Samsung to have the screen repaired today, they ask for proof of purchase, which we provide (Invoice off the site) and they will not accept as there is no IMEI number on the invoice.<br> The phone was registered via sms when received and they wont take that into account either. (Samsung) <br> I call Takealot and explain the situation and they say that they cannot help. <br> Really disappointed as I have been a loyal Takealot shopper since 2011 and have never been disappointed in the past, clearly buying items where backup service is required is not a great idea though.
