Bad Service

We opened two accounts, a social club and a savings account with Nedbank Pretoria North (Devine-Will social Club). We did not encounter any problems until we had to withdraw our funds in Jan 2015. The signatories were given wrong forms to fill and at the same time the bank failed to inform us that our savings account was closed. We were told to come back on the 8th of Jan when we got there they told us the funds were not available because they had to ask permission to release the funds from NCR. We went back again on the 12th and insisted we want to close the account and that they should give us all our money which was over R100 000.00 to no avail. We went back on the on the 14th after we were told a teller has been arranged to assist with the withdrawal. After being in the bank for almost 2 hours we got our money in cash and they failed to do transfers as we would normally do. The signatories were there to sign the forms to close the acount and now we get a message that the account has been handed over to their Attorneys and will result in a judgment against our names. Whose fault is it that the account was never closed?
