Frontier Communications They promised service they could not and did not provide Cincinati Ohio

So I moved into my new house in November 2019. Call frontier communications for Internet service and the representative asked questions to determine what service would be right for us.  She asked about mobile phones, iPads and streaming movies. So she said they could handle all 5 family members needs with their service.  Installation day came and the tech could not get the system to run at the speed to handle our volume.  

So after 2 weeks of slow service not being able to stream movies and do home work I called and canceled and explained that they did not do what they promised.  The representative told me that there were no charges and she would cancel the account and that there was no need to return the equipment.  So now after 7 months they have sent me to collections for something that number one they did not provide and second the representative said was taken care of.  

I've called numerous times and they all say that it has been fixed to today a reached a rude unprofessional person who said just get over it and pay the bill.  I am not paying for them wasting my time.  If they can't provide the service needed just say so. I will NEVER use Frontier Communications again!!!!
