So if a buyer flaunts a sellers terms regarding payment time as listed in that sellers terms and conditions they have every right to return any payment made after that time period has expired regardless of what  systems/timeframes that ebay offer to assist sellers regarding non payment and with the evidence of the sellers terms and conditions ebay would be bound to remove any negative feedback or refuse a seller non performance strike because the buyer flaunted the sellers payment policy timeframe......

A link please to the policy that states a seller cannot send their own collection firm (toe cutter) around to demand payment as per the contract that the buyer agreed to 1 day after the contract/sale was made if that is what the contract stipulated ????
