Can't buy a CD key ... Arrgghhh

For the past week I have been trying to purchase my 5th and final RAF-enabled account so I can make my 3/4 man teams into 5 man teams, but for some reason I can't seem to buy a CD key!

The first two keys I bought went without much of a problem, apart from an uncomfortable phone call with some American women asking very odd questions about myself and my WoW playing style (wtf?), but eventually I recieved my keys.

It then took me another week to finally "persuade" the same site to sell me another key for my 3rd RAF account - 15 emails later I got my key.

I then tried to purchase my final key for RAF account #4 and was instantly rejected claiming my purchases were "abnormal" - go figure.

I tried to purchase a key from 3 other websites, but obviously they were all linked to the same company and my transactions were cancelled and refunded within 2 hours.

After searching endlessly I found a German site that appeared to be of a different style to the previous sites so I nervously made my purchase.

That was a day and a half ago, my order is "being checked" and live support wont answer my mails - not a happy bunny!!

So I'm stuck at 4 RAF accounts now, itching to make it 5 so I can begin the awesome experience towards Northrend dungeons.

Anyone else have these problems when trying to aqcuire keys online, I could've gone straight out and bought off-the-shelf but it's 2009, I shouldn't have to - plus Multiboxing costs a fair whack to run anyway so every saving helps.
