Transfer service and customer service lied

Hello my name is [Edited: "Personal Information"] I have had service for over 2 years and was looking to move to Placerville ca. Placerville has difficult service areas so I wanted to confirm that I could transfer service to [Edited: "Personal Information"] because I didn't want to get into another contract and pay a lot more to another provider. I called and an agent said that I could get service at the address so I went and signed a rental agreement. Then I called back a few days later to make the transfer and a new agent said that I could not get service transfered. I'm very angry! I called and spoke to a supervisor and they contacted construction department and called me back saying that it would cost me $8000 to get Xfinity service to the address. This is completely ridiculous! The address is less than 1 mile from an Xfinity store and the agent lied to me and now Im stuck in a rental agreement with no Internet service. I would have looked for another place to rent where I could transfer service. Thank you in advance. Please respond as soon as possible.
