Extremely poor service

Nedbank! I don't even know where to begin. My account has been blocked continuously since the time I joined them in April. I visited the bank countless times then trying to figure out what the problem was. Only in May were they able to pick up that my FICA documents needed to be updated. I took my documents 3 times in the month of May (that being my updated ID doc, smart card). Till this day I've been calling the call center at least once a month so my account could be unfrozen because when I went to the bank they just couldn't pick up what was wrong. Its September now and already this month my account has been blocked about 5 times. I have a daughter that I have to take of and lately I'm even battling to buy her formula because my card declines due to being blocked, never mind not being able to travel to and from work. I am fed up!!!
