Closure of account

On numerous occasions i have had to indure disgusting service from your canal walk branch. My linch breaks have been exhausted. Little to none consultants available to simply close an account. It was not my intention to leave ur bank. But after such lazy and unapologetic service. I was forced too. Call center told to use the branch to change banking details. Branch says i must call the call centre. I refuse to bank bank charges for something I requested to be cancelled
