No feedback false information No email comms

I recently joined Discovery bank since joining I ve been given incorrect information numerous times and assistance has been poor just recently I was paid a less than nothing interest and call them to question it that was over a week ago and to date no one has come back to me . I told them I want them to email me a break down and explanation of the interest and was told they don’t EMAIL !!!!! How pathetic is that . It’s bad enough thier direct line is not toll free we MUST PHONE THEM TO ADDRESS ISSUES ON THIER SIDE AT OUR EXPENSE ITS LUDICROUS TO SAY THE LEAST
