How to contact support via text or chat

How do I contact support?  I was having my "Free Trial" of home internet cancelled and they cancelled my primary line instead.  It dropped the support call and immediately kicked me out out my account.  My phone can make emergency calls only.  Cannot call 611. My online account no longer recognizes my phone number.  Cannot link the account to my email due to account verification going to the phone they just turned off.  I don't have another phone to call.
