Billing

Good morning this is deep regret that I am writing this message. On November of 2023 I canceled my service with Xfinity at the store in Northfield Colorado. I asked the gentleman everything that I owed on that account because I explained to him that I was relocating. He told me the amount plus the equipment I gave him the amount and I asked him was that anything else that I need to pay because I wasn't going to be there. He told me yes gave me my receipt and then I left. Fast forward to the present, my hotspot subscription expired and it says I owe a balance of 102.49 and I was confused because I didn't have the hotspot before and I wasn't in the state so I'm trying to figure out how was I being charged. And the fact of the matter is the charge was from a whole year ago when once again I wasn't in the state. Although I love your services I really truly believe that I should have to pay for error that one of your agents made in order to get service again. It is also documented that I did close my account and it is documented the date that I close my account. But what is not documented is that they told me it was going to be an extra charge. I would like to know how do we come to a solution with this situation. Thank you in advance.
