So last week on Wednesday, I decided to be a good samaritan and help out a family that stated the needed gas money to get up north to make the call on whether to pull the plug or not on their mom who is in coma. So basically, long story short, I gave them 300 and got their truck's license plate, debit card number, a written consent saying what I did and the promise that I would get my money back, sister's california ID and the driver's license number. Now the contract stated I would be reimbursed on Thursday the 19th. Sadly I haven't been reimbursed and have been trying to contact them as I need the money for summer classes. What should I do here and any help/advice would be appreciated! Thanks guys!
