Canceling AT&T Internet and retributions

Has anyone ever experienced the following???.... Could NOT access my AT&T DSL for over half a month. Called AT&T (they no longer have a dedicated Internet service number) and waited for 30 minutes to finally tal k with a tech. Was told they could NOT fix my internet; ONLY SOLUTION was to UPGRADE to fiberPlan at TWICE THE PRICE. Up-selling lasted 25 minutes. Asked to be transferred to someone to CANCEL my AT&T internet. Waited on hold for a l-o-n-g time. A person in billing spent another 30 minutes trying to up-sell me. After THAT (PLUS) length of time and asking if there was any more info she needed, I indicated that I considered the conversation ended and announced that I was hanging up. ALL I TALKED ABOUT AND ALL THAT WAS DISCUSSED WAS MY CANCELLING THE AT&T INTERNET. Within two hours, I had a CLIENT called me to tell me that my LANDLINE phone - one that I had for over 34 YEARS and through which my clients/business ran - had been DISCONNECTED OUT OF SPITE. Never talked about disconnecting/cancelling my LANDLINE phone. She just did it out of spite. I could NOT access my internet with AT&T for over half a month - and still had PAID service left. I also had JUST paid my phone and internet for the NEXT MONTH. AT&T wants to charge a RE-CONNECTING FEE and won't even discuss refunds of services (PHONE AND INTERNET) that were paid for but NOT ACCESSIBLE. Has anything like that happened to you?
