New Phone Number for New Location

Have been a loyal customer for years. I've spent 2+ hours on the phone today with your mobile support team and haven't found a solution to my challenge. I have 2 mobile lines with xfinity and just added another today for a new phone. Originally, I had internet with xfinity in another state but since moved and the internet was spotty so we found a provider for less but still have the mobile lines. Xfinity would never let us update our address to our new home, however, under our account. Due to this, I could not get a new phone number linked to our actual home address in TX. I was told to get another number from different carrier and get back to them??? Please let me know someone can help me get a local or just a Texas number linked to the new line or help me cancel the line completely.
