Port landline phone number to another service

Hello, I am in process of porting my xfinity landline phone number to another service (Tracfone).  I went through Tracfone to request port process and provided them with my xfinity account information and a port pin of 0000 as this is a landline number and I saw this information posted. Currently on my Tracfone cell phone, it shows my landline number but it is not active.  My landline phone is still active.   Tracfone states that xfinity is not responding to request.  What are my next steps to ensure smooth porting of xfinity landline phone number? I want to make sure porting process happens and it works properly on Tracfone prior to any cancelling of service with xfinity. Thank you.
