.* Additional Charges: Jenny requested that I deposit on her checking account an additional $20-25k for her to purchase furniture, which I refused because I thought it was very strange, opting to give my card # instead.* Work Quality: Jenny never showed up to the house, she sent 2 people instead, she never mentioned she would not show up herself, she never asked for approval to send two others instead, they did not complete the job, and there were multiple unauthorized charges on my card.* Receipts and Expenses: Once I brought to Jenny's attention that we were 20k above budget, she refused for days to give me the receipts, saying that I needed to give her my credit card statement first.
