During a land auction at Parkwest Gallery their employee raised my paddle on a piece of artwork I expressed interest in . I went along somewhat reluctantly as I was uneasy about the sum of money. The same evening I tried to cancel with Parkwest Gallery and I was told all sales are final. I reached out to synchrony bank who finances the card and was told they cannot remove a preauthorization and only Parkwest can do so which I told them they were unwilling to cooperate in writing and verbally. Synchrony tell me by Friday May 7th the charge which is not yet posted would go away. This has not occurred and I continue to get conflicting actions from the bank. How can get a resolution ?
