As expected, problems with doing upgrade

OK, so I have pre ordered the Samsung S6 Edge, and as I have expected issues, I did it 3 times online.No reference number was send to me at all.<br> Yesterday I receive and SMS stating that I can confirm my order today, and receive a free cover and wireless charger. Since 08:00 AM I have been trying to do just that online without success. As the website was kicking me out<br> I then phoned the online upgrades department spoke to 5 persons , as I was now told that that the free charger cannot be guaranteed anymore.<br> I have now send them the sms's I received but still no feedback..
