Purchased a Ridgid drill sent in all the documentation received a lifetime service agreement verification letter in the mail. Two years later drills not working took it to a Ridgid service depot for battery warranty.Was told I have no coverage under the so called lifetime service agreement. I did keep copies of everything including the verification letter stating the drill, batteries and charger had all been registered under the lifetime service agreement. I have been fighting with them for days trying to resolve this issue. I can understand they need proper registration but I did that and received verification letter from Ridgid Customer service that my product was registered.Has this happened to others? Beginning to think their warranty is Bull!
