I want to know if we get scammed

I want to know if we get scammed today, our contract will end on the 28th of this month, we called costumer support , and we talked to someone who knows our adress and our phone number, and she said, we could have same speed internet with no contract for 5 years for 40$/a month, and said that we need to pay 150 for activation and the 50 will cover for this months bill, and the remaining 100 is refundable in 4 months. And next month we will only 40$ , and I noticed that the lady also signed in to our xfinity app, gave us a new account number, this this sound right?
