Transaction takes very long, Middleman is offline now. Switch MM?

[CountDown]

Hello,

so im currently in a tradeguardian transaction #77524. After there was a payment alert that took around 5 hours to resolve, our middleman is offline. For 2 hours after the payment alert was resolved. Since there is no option at all to switch a Middleman after confirming, is there any way to proceed now? The seller and I are literally loosing our patience and he is thinking about just canceling the transaction and selling it to another user.

Any quick solutions?

EDIT: Transaction canceled, no further assistance needed.
