Xfinity Support

I want to cancel all my services with Xfinity. I went to the store to cancel and was told I needed to call. Then was told I needed to schedule a call back. Tried to do it through chat and got the same message. The earliest call back is 5 days out. This is totally unethical, and costing me extra money because of your delay and process.  

Please cancel immediately and give me the instructions to return the equipment.
