Tired of Standards below standard service

All good and well I understand that maintenance needs to be done but unlike other times no notification to warn of the aforementioned was received. The call centre agent Natasha that I spoke to is absolutely *********** and unable to provide me with any solution other than, ‘so use a other bank’. So now I have waited from 12-3am and they still not back online😡😡😡 This is pathetic as they should obviously know the time frame necessary to complete the upgrade Now that I am here, on the 25/3/22 a deposit was made into my account and just as quickly as it entered it vanished. The call centre agent and her supervisor advised that it was transactions that was processed when I did not have the funds hence it was deducted then. I have no credit facility, so I’m order for me to spend 100 I need to have 100 available in my account and every debit is subtracted from my account as it is processed and then it is deducted from my available balance and transferred to my latest balance. So what they saying is in no way possible but after trying to make them understand for almost an hour I gave up when I’m actual fact I want and need my money but I’m the face of incompetence I lost hope.
