Dear all, Ive sold some domains and the buyer paid by Bitcoin in 2 transactions. I transfered domains, but BTC transactions are pending now for 5+ days, he seems is not doing anything to fix that, because he was cheap and sent a 1000 and 1500 satoshis fee. He said the Bitpay said that they couldnt do anything and it will confirm in a few days. My transactions went from 10K+ in a line to 100K+ in a line today, so I think this will never confirm. Ive read somewhere, the unconfirmed transactions can be reversed or resent by paying extra fee. If not will they be dropped from the pool in 21 days?

thank you for all your answers in advance,

BR

ps: here is link to the 2 transactions :
