Billing Issue [Edited]

Let me start out by saying I had Comcast for over 10 years for internet services! Maybe a issue here and there nothing major! Was happy with my internet services but they convinced me to get the bundle deal cell & internet to save money! So excited I decided to upgrade and swap my phone for a new one ( samsung galaxy 23 ultra paid and owned) got me the new one. Anyways was told I wouldn't pay anything for my bill on July because I was gonna get credit etc..  well 2 weeks later they charged my account my old bill called supposedly got credited and I wouldn't have to pay for the month of August because I was credited back etc. We'll  July 21 come home my internet not working got online talked to a rep. And they say my internet has been canceled  they can't give me a reason or who canceled. They can't give me back my old phone but they can take back the new one and give me credit. Spoke with a supervisor and he said I can't return the phone either that I was missed informed by his employee/coworker.  That my monthly bill w a s gonna be around 80. When I was supposedly gonna just pay monthly fee for payments on the new phone and taxes the 1st years the line was supposedly free for a year if i had internet and cell.  Now they want me to sign up again for internet and it's more than what I was quoted!!why should I be in held responsible for a contract!!they canceled my internet not me!! I don't recommend this company it's changed so much through out the years.
