Premier banking sending me in cicles

I am so disappointed in the premier banking service i am receiving. I am meant to have an option to chat to a banker on my app for queries, however this chat function is not available to me and I have been trying for almost 2 weeks to get it sorted out.

Calling the preimier banking team I get put through to the bank app support, they then cant see whats wrong and put me to online banking support. They in turn send me back to premier banking. I really cant go in circles anymore, is something so small really that impossible to fix? I have emailed support about it, got no response. Also the twitter support RBjacobs completely ignores my tweets.

Please live up to your slogan and help me!
