Very poor service and support.

I have been a standard customer for the past 40 years, but lately I find their service and support absolutely pathetic. On two occasions over the past month my account was allegedly overdrawn which I queried shortly after the sledged I transgressions and was informed that the online balance can take up to 2 days to to reflect on the on-line app. When I disputed this, I was informed that this happens when you use a cheque card. I tried explaining that my card would be rejected if there was insufficient funds as I do not have an overdraft facility. Yesterday I noticed that I was erroneously charged overdraft fees. When I tried to rectify this I was told that my account must have been overdrawn at some stage. I was told that I could not be helped. I will be closing my account shortly. Most irate and disappointed customer.
