Login issues

I can't seem to login to my account. I enter my phone number, the only one I have, and get a message that phone verification is unavailable and I need to enter my email address. I've tried every email I have and always get a message that the combination does not exist. So, I tried making a new account with the phone no and most likely email I would have used and get told that account already exists. Is there a way to contact someone to get this straightened out?
