From a quick look at your feedback profile, I think the hold maybe to do with all the negative feedbacks you've received.
To be honest with you, I've never seen such a low % feedback score, or so many negs received in such a short period of time.
You may find that payout will be held until any case for item not as described / not received is resolved. If the £65 doesn't cover the above costs, your back up source will be used, usually your bank account.
