The wall is the giantic debt that comes with the acquisition of those subs. Yes they are getting paying customers but from what has been the track record with these deals the benefit goes to seller and not buyer or customers who are sold.
These areas are between a rock and a hardplace. Either the stay with VZ and get forgotten or the get purchased by a smaller carrier and have a chance of being screwed by bad service and no upgrades.
Good luck to Frontier refinanacing that debt in the future.--
