how do i receive my free xfinity wifi pod

when we signed up for xfinity we were promissed 1 free wifi pod. its never been sent, we have one location that needs better coverage for a wifi camera. this camera constantly goes in and out of connection. i just asking what was promissed. i understand there is a process that checks our home for connection strength. i believe it has been done at our home. but the camera continues to lose connection due to the poor strength. we have been a very long standing customer. please help
