Please help! Frontier internet is a scam

Hi reddit, has anyone else ever had terrible customer service experience especially with internet service providers like Verizon or T-mobile?

I‘ve had Frontier’s eero internet plan for about two years now. A few months ago I noticed that my plan’s price went up; for reference, I used to pay $30 a month and then they were charging me $60 a month for no reason. I called them and they gave me a discount which brought it back down to $30/mon, but the agent did something with my plan and I got an email saying I have equipment to return. I called them again the next day and the new agent confirmed that I indeed did not have to return any equipment since I didn’t change my plan(?) and that they would flag my account so that it won’t charge me for the missing equipment return fee which is $150.

Fast forward to the next month, the $150 fee was taken out of my bank account anyway 🤦‍♀️ and so I called them again and the third agent tells me that they’ll refund my $150 in credit form to my frontier account and that they’ll prevent the future $150 fee from being taken from my account. IMPORTANT NOTE: while I was troubleshooting with this agent, he was rambling on about wi-fi security and Frontier’s additional services, to which I tell him many times that I am not interested. So we get the billing issue solved eventually and I hang up… to then receive an email 5 minutes later about a “purchase confirmation for monthly wifi security plus”. This agent had placed an order for an additional service to my account without my consent and I had told him no multiple times. So now I have the billing issue with the equipment return fee and a new issue with the wi-fi security plus service. Oh my goodness, I called them a FOURTH time and to cancel the wi-fi security service immediately, which the new agent did.

Fast forward to this month, I get a notification telling me my wifi account is suspended. Guess why? I was charged the $150 unreturned equipment fee AND the wifi security plus (that I had cancelled) despite all of my calls. I’m so lost right now and I have no idea what to do, calling Frontier customer service is like speaking to a wall. Half of the agents dont know what they’re doing, and the other half are actually trying to help, just for the system to charge me anyway.

Please give me advice on what I should do and who I need to talk to at Frontier for this is be fixed once and for all. I’ve been doing this back and fourth with them for months now.
