Unable to use the app at all

I tried to log into the app, but there is no link to log into an existing account. I entered phone number, text code, and email as prompted only to get an error message that my email was already registered. I KNOW THAT. Emailed back and forth with customer support and started to feel like they were trolling. No help at all and didnt seem to comprehend the problem. Finally they said I should delete my account and sign up again. Sure delete it. Not sure if I will try again
