Xfinity Device Payout

I have been trying for 4 months to get my prepaid cards sent to me for the Xfinity Mobile Device Payout Plan.   Everyone I speak to tells me that my paperwork is complete and that it should be taken care of in X number of days but I still am listed as "pending" in the tracker.  What can I do to actually get this taken care of?  I'm starting to regret my choice to switch to Xfinity mobile and am close to switching back to my previous provider.
