Thyme Bank - shocking service.

Shocking service from the call centre! I sent through my new proof of address document as requested, and because I didn't answer my mobile phone during a meeting, they closed my case and didn't want to help me further when I called their call centre. They said I need to email the POA again – what? They already have it! What did you do with my document in the first place. Mismanagement of my personal information? The unhelpful lady was reluctant to share her name or at least spell it to me - it shows they don't care! I'm ready to close my account if this is not resolved.
