Account closure

Two years in a row I’m experiencing problems with this bank. This year on the first I ask for my account to be closed since I have had enough, I was told there are pending transactions which will delay the closure, I should wait 3 to 4 days, and there was also a refund that I should receive. Kept following up via the secure chart, being told the case has been resolved escalated. Last week I was told I needed to wait 5 to 7 days for the closure to be completed. Today i am following up. And I need to pay pro-rata. I followed up just now 2 agents just dropped me off. This really poor service 😡😡😡😡
