Fixed a billing dispute by mailing a paper letter to my cable company's legal dept
After 3 months of phone and chat arguments over a $160 overcharge, I sent a certified letter to their corporate legal address last Tuesday with a copy of the bill and my notes. Got a call back within 48 hours offering a full refund plus a $50 credit, which never happened with any of the call center reps. Anyone else had luck going the old school mail route when the frontline support just keeps giving you the runaround?
