Lack of customer service

Where do I start? Not to go into specifics but I had issues out of my control from Xfinitys end that left me without service for weeks after moving apartments and upgrading my internet plan. This on its own was an unbelievably strenuous process but it eventually worked out. Fast forward to today and I’m having billing issues. So, since I recently underwent medical operations and can not speak over the phone for a few weeks, I’ve been trying but failing to come in contact with ANY Xfinity personnel. Xfinity assistant live agent chat? Never seen anything like it. Live agents will LITERALLY cycle around every few minutes reading my inquiry and passing me off to the next agent without even saying a word, I’ll go through 5-7 agents all completely ignoring me before I just end the chat. I just get passed around like it’s a game of spin the bottle. Also tried contacting Xfinity on here via DM and was also completely ignored, they just left the message on read. I’m quite dumbfounded here to be completely honest. I’m aware Xfinity has and always will be known for HORRENDOUS customer service, but this is beyond bad. Never would I assume a company would even be ALLOWED to just flat out IGNORE a paying customer with legitimate billing concerns. It’s actually so unbelievably asinine I don’t know how to appropriately express my frustration. Any thoughts on what I should or even COULD do? Thanks in advance. Gotta love this company right? Smh. This has gotta be borderline illegal in someway
