NETSURFER TABLET

Before i have purchased the Netsurfer tablet, i have bought a Vodacom tablet for my husband, which i am very happy with. The memory is great. Then i heared about the Netsurfer tablet, i went to PEP Meyerton and ask which tablet is better, i was told the Netsufer is much better and the memory is great and and.... so i purched the damn Netsufer tablet, and didn download any other apps on it, and i did put 8gig memory card...NOW THERE IS NOT EVEN ENOUGH MEMORY ON THE THING FOR THE UPDATES!!! i would like to know whether i can change the tablet for a Vodafone one, because i was mis informed about the product.<br> <br> Regards,<br> natashia <br> ***
