Nedbank No customer service!!!

Nedbank has suspended my online ID... I have been calling in non stop for the past one week now and no one has gotten back to me . They have said an investigator hasn't been assigned to my case , so how did they investigate in the 1st place to come to the conclusion that my account needed to be blocked . How does this make any sense!!!

This isn't the 1st time I am having issues with nedbank, I called the ***** devision in November last year to block my online ID as we had a house ******* and my phone was ****** and had no password. When I went into bank there after the guy had canceled my bank cards after I repeatedly told him I still had my cards with me ... Thereafter he wanted me to pay card replacement charges per a card, I tried calling the customer care and they were of no help !
