Insanely bad treatment for existing subscriber

Ordered an iPhone 6s, received the device on launch day with the wrong sim card and over priced package. Requested a package change, took almost two weeks to collect, through endless calling I eventually decided to cancel the new line within the 14 day return policy. Took a further week to collect, and an even further week and a half to cancel.<br> <br> I tried applying for the exact same phone through the iStore was declined due to \lines allowed exceeded". As the line with Vodacom online had not been cancelled when they said it was. Tried re-applying with confirmation of cancellation and I am still getting declined and cannot re-apply for the next 90 days. <br> Bare in mind"
