Extremely poor service

I have been struggling since Sunday to resolve problems for my business banking. On Sunday I talked to Roxanne digital banking who could not help me and escalated the problem to the technical team and said it would take 24-48 hours. On Tuesday I spoke to Nerissa who said that I should wait for the technical team to contact me (spoiler the technical team has still not phoned me). Then on Thursday I spoke to Mitchell Ambrose who promised that he will do more investigations and then phone me back the next day between 10-11am. At 12:30 he still did not phone me back so I decided to go to a branch to talk to someone in person only to be told at Irene branch that no one there can help me and that she will help me to make a call to the online department at the branch. So we did that and then I spoke to Lucian Townsend who also could not help me after our 30 min conversation and then told me to email him screenshots, which I did and then got one email back whereafter I sent him more screenshots and he never rep****. It's now 18:15 and I still haven't heard anything. Extremely frustrated and annoyed by this utterly poor service!!!!
