Pathetic service

Direct axis decides to do an early debit order on my account without informing me , leaving my account on a deficit . Trying to call their call centre is also pointless as they just hang up on you while you are busy on the line with them . I signed a debit order mandate for a reason . Why am i been inconvenienced like this . My account has never been on a minus until now . YOU ARE BULLYING YOUR CUSTOMERS AND ITS NOT RIGHT , Please stop with this nonsense behaviour .
