Worst service ever from private banking.

I've been trying for over a week to upgrade my account.ive spent over 150minutes calling in to get from premier banking to private clients, I was told I over qualify for private clients and then passed to private wealth then wealth said it's not enough month then I was passed back to private clients who said someone will call me back after nobody called me I called again and was told the lady on upgrades was busy and will call me back I'm still waiting each time I call in I get passed from pillar to post. Can someone call me and upgrade me please or do I need to go to another bank.
