BAD CUSTOMER SERVICE, THE WORT NIGHTMARE - NEDBANK INSURANCE A ****

My experience with Nedbank, after being with them for more than 5 years , is pathetic . I chose to close my nedbank account as i was no longer happy with their service, upon closing i also had an insurance policy which i now needed to be taken over for the debit order to go off on a different account,. I called in , and they advised me that i should first let the last charges for the month and the policy deduction go off for October and thereafter , they will put me in contact with the insurance dept to take my debit order to a new acc and close my nedbank, Fine, the policy went off, the last bank charges, i then called in the next day and the guy told me all is good, he closed the acc and put me through to the insurance dept to switch the debit order , never got through, kept getting cut off, called in again and again and finally got through. The guy on the phone told me that i must send an email with the proof of banking details for the debit order switch, i did that too. I receive an email, that firstly, my policy didnt go off for Oct. I then send them the SMS that it did and explained what the guy said and everything and they reply again on email and says, that the policy debit order cannot go off on another account, but only if i bank with nedbank and from a nedbank acc. I have since sent emails, asking what happened to the debit order that went off for Oct, and how can they tell me after i closed the nedbank acc , that i can only use a nedbank acc for the policy debit order , i cc'd all complaints depts and no reply to resolve this issue, they blatantly ignore my emails and give, a simple one line reply to say your debit order was unsuccessful, no reply on my query, clearly they dont want to read and choose to ignore, their mess up , I WANT ANSWERS AND MY QUERY TO BE LOOKED AT
