Bad Customer Care Service at Branch

I waited for 3 hours within the bank to cancel my account. When it was finally my turn they refused to cancel my account despite me having all the documents needed to cancel. once I asked them to indicate to me where within the contract it says I'm not allowed to cancel my account and what documents were missing I used to be told it had been my problem to work it out. Horrible service and horrible attitude overall. Avoid any quiet association with this bank.
