About 50 days ago, out of nowhere, I couldnt logon to their app or website ( despite entering my correct User ID & password ), they requesting I want their access code sent to my cell as a text or a robo phone with a verbal code. Ive requested both almost daily since then to no avail. No code is ever sent. And their phone numbers are not blocked & no issue with my cell provider.i requested customer service help 7X, then to Customer Service management, then to Member Concern management, IT Management, 2 case # s & nothing ever gets resolved. Ive even deleted their app & downloaded a new one. Its their issue & they have unbelievably terrible customer service. Ive been far, far more then patient!
