I've been using Bitcoin for several years now, I recently decided to try and invest in some Alt-Coins. I created an account with BTC-e and followed their instructions to fund my account with £1500 via SEPA transfer. The instructions requested a 'details of payment' which I assumed meant a payment reference, I could not fit this in the payment reference box with either of my bank accounts (Halifax and HSBC) using online baking. Instead I used a reference of my BTC-e username. Immediately after making the transfer I opened a support ticket explaining what I had done so they could easily trace the payment, they responded quickly stating there might be a delay.
I made the transfer on the 30th October 2013, since then I have had nothing credited to my BTC-e account. All further support tickets I have opened have either been ignored immediately or ignored after providing them with further information they requested. I have sent them a screenshot of my bank statement clearly showing £1500 leaving my account on the 30th to their account. I have even sent them notarized copies of my passport and a utility bill.
I really don't know how else to proceed, any advice would be much appreciated.
What you need to do is contact your bank. While stealing bitcoin may not yet be a crime since it doesn't have a legal classification, stealing money is and typically your bank will quickly probe in to and find out what happened.
More likely this is a mere error and when your bank starts probing the will find the administrative mistake.
