changing my mobile number to a different area code

I recently moved my cellular line from Verizon to Xfinity mobile. When switching I also opened up a 2nd line on my account to be used as a business phone. I am local to the Philadelphia area but the business I am opening is in Tampa, Florida. The only reason that I decided to switch my service to Xfinity is because I was told with 100% certainty by multiple individuals that once I had the second device that even though it would be assigned a local number initially I would be able to call in and have the phone assigned a number with a local area code for Florida.

Since then I have spent several hours with customer/technical support team members at Xfinity who are telling me that there is nothing they can do for me and that they cannot assign me a new number. I was lied to by multiple people who had no issue taking my payment and giving me false information that I would be able to get a new number to do so. Any help or assistance that someone has who has been through this would be greatly appreciated.
