I keep getting billed after canceling

This was resolved within 24 hours. The support agent was knowledgeable, empathetic, and understood the issue fully. Much better than the last conversation I had on the phone. This time the issue was actually taken care of and I received the proper confirmation. 

This happened to me and I have been charged for 5 months and told "Too Bad" when I expected a refund.  To be clear, I have called 5 different times over 5 months to cancel my account, and visited their local office 2 separate times in the last 2 weeks.  Every time, and they said they cancelled it, and 6 of those times, they did nothing and I kept getting charged.  No cancellation emails, no refunds, no nothing.  Then i get another bill.  The second time I called, they apologized on the phone, game me a $90 credit.  Then, the charged me full price, again.  All 5 times they told me they cancelled my account, and all 5 times they kept charging me, at $150 a month.  So finally I marched down to the store and started yelling at people, nicely, and was told it was not cancelled.  Then he asked if we had used it since July when i cancelled it, and I said that didn't matter, i cancelled my account and the hardware was still plugged in but that we had AT&T Fiber installed in May, which was faster and cheaper the Xfinity.   

Then I showed him all of my billings, and they said we are sorry, but you still had the system and too bad, we are not giving you a refund, for 5 months.  Then I asked for a manager. He told me he would ask for a refund and then actually cancelled my account and I received, for the first time, a "your account is cancelled, please return your hardware email" which i did 4 days later.  Still no refund.  Then i go down again, to cancel my business account with them, and tell them they have not given me a refund, after telling me it took 24 to 48 hours to process.  It had been 178 hours.   The manager says just a minute, and I get an email for a $150 refund.  1/5th of the amount they have billed me since July.  I said that is [Edited: "Language"] and I wanted a refund.  The manager said that he would put in an "Order" for the full refund but that he didn't have control and I should HOPE that they will give me a refund.  24 hours later, an email arrives saying that my refund was denied.  

Really sad to see this garbage happening with other people is common with Xfinity.   A Google search shows story after story of this.
