Worst service ever

For 3days am still fighting with standard bank to fix my account. They blocked it for no reason after calling and verifying its me. Am sick and down with Covid and need to access my finds to buy medication and am sent from pillar to post. Was sent to ***** department which said its not about ***** but person who blocked it works on the online department. I've sent countless emails and stayed on the phone for hours but still am not getting help. As a person whose having shortness of breathe and staying on lengthy calls its very frustrating. Can standard bank fix this asap as I need the funds to be buying my boosters
