Customer service chat scam

There were a lot of network outages for supposed upgrades in my area and when the network was back up even more problems getting reconnected properly. I reached out to customer service via the app chat due to the service interruptions and issues. The agent seemed helpful and said I was eligible for an increased internet speed. I should have thought more about it and asked more questions but I thought he was helping me out. Anyhow - I accepted the plan update via text and even though there were no charges disclosed my bill went up around $30 per month. I contacted via the app chat again to state I was upset about this and wanted to complain about the agent’s transparency and also restore my service to the previous settings/rates. Well there wasn’t a ton of clarity provided other than they’d put in a dispute and transfer me to a supervisor for the complaint even though they have in their records I agreed to the change. Since the entire conversation was in a chat it is also easy to tell there was no price increase discussed. Anyhow during this chat I start getting automated calls from 888-984-6439 stating it is the call back I requested. I don’t hit any of the offered selections and hang up. Ask the agent if I should be getting any calls or if he is calling. He says no. The calls keep coming despite hang ups/declines. I block the number and search online to find that Comcast customer service agents also work for scammers and give away your info. This didn’t feel like a coincidence although I haven’t seen a story where it happens at the exact time of the chat. The supervisor supposedly picks up the chat which is compromised for lack of a better term so I just politely end it and say that I will see what happens with the dispute and don’t want any official complaint. Maddening that I reached out for help and now I’m worried about being hacked or scammed compliments of Xfinity not properly vetting or reacting to these reports about their employees or contractors. I wish I could get rid of all their services now because it feels awful that my info is basically served up to scammers despite me being a paying customer. I’ve read a lot of seemingly canned responses to posts like these that suggest starting a new chat with different employees? I’m not sure that works for me. I’ll be filing complaints with the FTC and FCC (unlikely to make a difference but checking the boxes) also going into the local office when I’m able to try to get resolution. Very upsetting this has me on edge.
