Yaga 'make an offer' feature enable buyers to renege on accepted offers

Yaga introduced a 'make an offer' feature where buyers can offer a lower price, and the seller can then decide to accept the offer. However, once accepted and even though there is agreement on the item and price, Yaga the also requires the buyer to place an order. Many buyers do not as they get to change their minds even if the seller accepted the offer, with no accountability. Even if other buyers can still buy the item, just seeing if an offer gets accepted and then reneging on the agreement is becoming a trend, enabled by Yaga. I have written to Yaga before on this issue, to no avail. To enable buyers a second bite at the cherry and allow a change of mind once an offer is accepted is simply enabling unscruplous buyers and prejudicing bona fide sellers. Please Yaga, fix this problem; this used to be a good and fair trading platform.
