Hello today I went to the post office to put money on my visa card. but somehow the post office's employee has told me your balance is negative $-221.60, after that went to home and i logged on my account to see if that really happened, unfortunately it showed me the same as post offices employees said to me,and now I am very frustrated ! it is unfair like having a negative balance while you did nothing, and I knew before creating this visa it cant be used without putting money in the visa, it is really annoying !! any solution to this issue?
