Hello, I have been my grandmothers caretaker for 10 years now. Since the beginning she has given me her credit card to buy items she has needed as well as food and helping me with my bills. Now all of a sudden I am being accused of fraud because she says she never gave permission to use her credit card for certain items. Even though she hands me her card every time for purchases. I am at a loss of what to do because I sadly never got anything in writing, never thought I had to cause we had such a good relationship. I just dont know what do to.
