They put back and future credits on my account because I wasn't receiving the quality of service that they promised. You gotta remember; Sprint is bound to the same contract that you agreed to when you activated your account with them. If they are violating your contract terms, you have every right to take action against them just as long as you have held up your end of the deal by paying on time and not abusing the service by tethering illegally, etc... Give them a call, have a network ticket put out for your area, and most importantly, BE PATIENT, because unfortunately, a complete network overhaul doesn't happen overnight.
