pre-order not working online

good day<br> <br> i do qualify for an upgrade, when i went online too [URL Removed] too pre-order my galaxy S6 edge gold, i'd keep on getting technical difficulties and can't even log into my account. this means that vodacom is rejecting me from doing the pre-order which means i do not get the wireless charger and cover bundles with the pre-order, which is unfair too the consumers. this is not good client service. how can i pre-order and approved(upgrade) for the wireless charger and cover as advertised???<br> <br> please assist.<br> <br> thanks
