NEDBANK IS A *****

so yesterday i went into nedbank to deposit R65grand into my account. great service, i was in and out. i then done an eft payment. 1st my limit was at R20grand , i had to phone in for them to change it due to me not remembering my password. i was on the line for over 20min due to the fact that they kept transferring me to different people to help and they kept cutting the call. anyway it was sorted due to a consultant helping me. today i received a call from the call center stating my account is 849 in arrears?????? for what????? the lady then told me that is the charge for depositing cash and doing a eft payment? i mean what in the world???? when i opened up my nedbank account things like this was not explained to me..i am so upset . does nedbank think just because i deposited R65grand into my account im a rich woman??? words can not explain how upset i am , i was under the impression nedbank is a great bank but i was totally wrong. i am officially changing my bank!!!!!
