I have one hundred dollars in my Guilin bank card. How could it be gone for no reason?

Bank card charges annual fee 10 yuan. If the deposit is lower than that in 300 yuan, an annual management fee of 12 yuan will be charged according to 3 yuan. If you still open SMS reminders, you can go from 2 yuan to 24 yuan every month. A year is always *** 10+ 12+24, =36 yuan. Three years later, 100 yuan was gone.
