Costing me thousands due to a mistake they can’t figure out!

I have not been able to do a simple transaction or get it resolved for 2 days now as the payment should’ve been completed yesterday after being advise linking my accounts would be active within an hour and to date have not paid my invoice or withheld my contractual obligations due to Standard Bank’s incompetence and will be invoicing the bank the additional charges due to their failure. I have been a client for 10 years and am moving my funds elsewhere this is completely ridiculous
