ACCOUNT ON HOLD WITH NO EXPLAINATION

My account has been put on hold pending an investigation because I received funds from Nedbank. I have called numerous times and was told an investigating officer would call me back. Your own processes were not adhered to. I was not informed my account was on hold, my card just kept declining despite having funds in it (Continuous embarrassment`). Its end of the month and I have debit orders that come out from another bank. I understand the need to verify things, but this is crazy four days without access to my funds. How must I live @Sim Tshabalala @standard bank there must be a better way to do things. This is beyond frustrating.
