Best offer auto rejected, then manually accepted

[interpol224]

Did 3 offers to a seller that were all auto rejected, purchased similar item from another seller only to find out later that night the original seller had gone back and accepted my highest offer manually 2 hours later. 

Now I'm stuck with paying for an item twice or having a strike.

Is there anything I can do other than hoping for the seller to respond to my messages of wanting to cancel the purchase?

That could well be it, papermoon! I think you may have solved it.

That sounds like the most feasible solution. Maybe the seller's counter offer was exactly what Interpol made in his final offer.

If it is a counter offer then Interpol is fine, he doesn't have to accept it and won't get a strike.
