Horrible service

<p>My credit card limit was increased later I was told there was system glitch & I was not suppose to get the increase. Ever since then Fnb tells me my account is overdue and so far 3 deductions have been made from my transactional account. This is not fair who pays a credit card 3 times or a month? I need explanations on this cause I don't understand, when I call no one can assist me,they just transferring me to wrong people.</p>
