### 1/5 — Customer service terrible

*2026-07-01, version 6.15.1*

Been trying to email them for days. I’m getting emails back but they’re saying to log into my account and I’m up-to-date but they’re seeing a totally different screen than me. Nobody will get back to me or if they do they’re saying the same thing. I want to cancel their account, but there’s no option for me to do so in the app or online believe I was scammed.
