Dear Valued Customer,

Thank you for contacting MtGox Support. We are sorry for the delay in getting back to you. Due to a high volume of ticket flow we are unable to respond on time. We are working on it real hard to solve the tickets as soon as possible.

We have checked regarding your withdrawals. Your withdrawals are in the "confirmed" status. Due to the Japanese holiday, all the withdrawal requests have been piled up and we are currently working to catch up the delays. So we kindly request you to bear with us. We will update you once it is processed.

We appreciate your patience at this time and we offer our apologies for any inconvenience that this may have caused.

Best regards,

I hope they are hiring new people and installing new infra in order to cope with a lot of withdrawals, and support tickets.
According to the 25 days estimate, I should be able to get my JPY cash on the Feb 15th/16th.

I still trust them but come on with all the cash you make hire new people!

Even if Mark is paranoid and wants to hire only trustworthy French men, he can afford a headhunter and offer high packages and the plane tickets to Japan and cameras all over the place at the office.
