Moving Services

I have Xfinity internet services and have been unable to move my services (of 3 years) to the new address because the person who previously lived there defaulted on their bill before vacating the property. I work from home and need my internet services. This has been a severe hardship on me financially. I have called customer services who told me there was a “fraud alert” on the property due to the previous occupants, and I needed to go into the office to resolve it. I immediately go into the office where they indicated a ticket would be created on my behalf and someone would be calling me within 24-48 hours to rectify the situation. Within that time, I received no callback or email. I called the customer services number to check on the status of my ticket only to be made aware no ticket was created. I provided the customer service representative at the store a copy of my lease to prove I am the owner. I was pushed to several different departments that were not equipped to assist for over 2 hours. I am getting no resolution to this situation and I want to know who I can complain to about the services I am not receiving.
