Incompetency of banks

I have a Nedbank account and was blocked since Saturday. Have phoned customer services many times and visited the branch nobody can help. On Wednesday 2 o clock in the morning R394 was deducted from my account Nedbank cannot trace the reference and put me on a further block. We are pensioners and need the money. My wife is in a wheelchair and needs medication The last reference we received from Nedbank ***** was ***1. Their investigation will take a few weeks. In the meantime we tried to get hold of our branch manager here in Moorreesburg and told him that I want to cancel my complain about the R394.00 that was deducted from my account to see if my account could be activated sooner. We still waiting for the branch manager to come back to us. We are both SASSA grant receivers and our income is just enough to cover our rent and electricity. I am 63 years old and have a heart condition. This whole setup send my blood pressure sky high. I hope you people can help us here-in, please. Johann Koekemoer, ID *** ***866
