CoinCola supports disputes based on evidence supplied by trade participants and by their reputation.
Disputes can be started half an hour after the payment is marked complete.
After the escrow has been released by the seller the trade is considered finished by CoinCola and cannot be disputed.
When a Bitcoin seller is unresponsive, CoinCola will release the Bitcoin to the buyer if the buyer can provide a valid proof of payment.
If the buyer is unresponsive after starting a trade, the escrow will be released to the seller by CoinCola support.
