Here is my letter, I have applied for a refund for an order placed in October, will update this thread with progress:
03.04.13
Hi, I have 2 pre-orders from BFL dating to October, I remember it was then clearly stated that if BFL Labs ASICs do not ship by January 31st, then a refund will be given.
Due to current family circumstances and unforseen delays from BFL Labs, I am in an urgent need for a refund.
Please could you process a refund for the 2 orders below with great urgency.

Order 17xx ($787)
Invoice 51xxx ($20 + MiniRig to 12SC Singles conversion $15677)

Total: $16484

Original sources of payment:
PayPal: xxxxxxx@hotmail.com

Barclays Bank: xxxxx
HSBC Bank: xxxxx

Please process this refund with great urgency as I have unforeseen family circumstances.

Thank you.

BFL Labs has sent me a full refund via PayPal, surprisingly PayPal has not charged a fee which is great. BFL labs has also sent slightly more than what I asked for which is also great.
