Account closed yet still harassed

I closed my account with Netbank on 6 March, every week since then, often twice a week, I receive a text message from them. They either tell me my account is overdrawn and I need to sort it out immediately or that there is funds in the account for collection and I must sort it out immediately. I have tried calling ***and telling the consultant to ensure that the messages stop but it never works!<br> Today, I was told just to ignore the messages! So basically, I must just, for the next however many years of my life, just ignore a weekly, sometimes bi-weekly text message telling me I'm in the wrong? I have spent more money on phone calls to this pathetic bank than was left in the account so they should actually be refunding me money! When I closed the account I was informed that there was only R6.00 in the account and that the bank would just keep that money which shocked me as well!!! I am so glad that I've moved to FNB!!
