As much as they love to do another great promo to bring up customers, they gotta maintain the service that flows smoothly. Doing another promo would not be a such a good idea at this time.
I am not sure they will have the fall promo all cleared up by then. With all the additional problems that were created by being able to change existing plans to a new plan on next renewal date. There is so much that needs to be taken care of before then offer another promo
