So the issue of transactions not being process on August 26th resulted in some bitcoins being sent to an expired address at an exchange.
Whilst transactions that were destined for my own wallet were processed eventually, so were these time sensitive transactions.
I've opened another support ticket at MtGox but it's now been 4 days since I've heard anything.
I know I'm small fry but I'm more than majorly peeved that I've not heard a peep from them regarding this issue for over a week.
It's like they think that just ignoring it will result in me going away, well bad news. I'm not going away until it gets resolved.
Have you checked with the other exchange? If I understand correctly, bitcoin addresses don't actually ever expire, so although they haven't tracked it to your account, they may still have received the bitcoins and can apply them to your account if you can show it was your transaction? Worth a try, anyway.
