CT Class Action over 1 day late fee

I have been a Sprint customer for nearly 20 years and reside in CT, looking for fellow CT residents who were previously Sprint customers who received notices throughout the merger that none of our benefits were going to change and are now harmed since T-mobile by their own choice considers a bill late even if 1 day which was never the case with Sprint. I called their Maine call center on 3 different occasions and their employees, even supervisor Mary, stated it was CT state law that forced T-Mobile to have a zero day late period. Which I knew was wrong and have now been confirmed to be correct by T-Mobiles executives, Team CEO. The Maine call center is supposed to be being notified not to lie to CT customers by stating it is *not* T-Mobile who is forcing the 1 day late policy but that it is CT law. This is 100% false, as now confirmed in writing and recorded conversation by T-Mobile executive - Team CEO.
