Chasing my tail with support - three business acccount about $1000 a month... OMG

About 10 years of Comcast/Xfinity for office including VoiceEdge, Internet (100/10), TVs and "phone" - have tried getting an account rep. They are great at signing you up and adding services. Now nearly 10 years later, bill is very high, approaching $1000 a month. ATT Business offered me Fiber 100/100 with business phone built on RingCentral. As hoping Comcast would offer retention benefits (lower my bill) and train my staff on the complicated VoiceEdge... Cannot reach anyone and level one support when calling a 800 number results in pointless conversation with people who do not get it. Comcast has fragmented service and this is reflected in both billing, account management online and lack of unified support for a business. I cannot even find my length of contract online... There is not brick and mortar office to obtain service and ask questions. Feel trapped by this monopoly. Comcast folks, you need real humans to evaluate your clients online account management and provide a customer service office for regionally close customers. I feel that I am in a third world country or a surreal locked-down future with the semblance of customer support and professionalism. its a veneer with maximum profit for a company that is too large and poorly organized.
