So, here is how it has come to resolution.
I got an email from the loan agent this morning, saying he was on it. He was having a few staff at that branch work on it, and was involving the merchant company. He says he will have it resolved by afternoon for me.
In the meantime, I am chatting with my brother about my legal options. He is an asst DA in Ohio, which is not Utah law, but he has some knowledge and gave me ideas ranging from criminal charges to civil.
A few minutes ago, I got a call from the same girl that I had to deal with yesterday twice, in which she plainly told me that she could not do anything. My loan guy had lit a fire under her apparently, because she decided it might just be in her job description to contact the merchant company and the store. They conference called, and now they have miraculously found the erroneous transactions, are so sorry, and will get them into my account in 10 business days. She made sure to let me know that the owner of the shop was helpful, and it was an error on the part of the merchant company and not on the store's part. Fine, whatever. He was so very not helpful until I told him to make it right or else.
Anyway, happy ending. Got a call from the asst from the loan agent right after to make sure I heard and to tell me they appreciate my business and so sorry it happened. FWIW she is actually great and I have always had great experiences with her and the branch in general.
If I had to sum up what I have learned, like a cheesy 80's sitcom/cartoon, I would say:
1. Never use a debit card, use credit and pay it off each month (which I have always done for the business, just not personal)
2. I need to be 100% on-board if any of my patients ever have an issue to help them resolve it and make it right.
3. The FFA thinks I need to indulge in bestiality. Kind of a lot.
4. I am just glad the actual people at my local branch helped and cared. It means a lot.
