Query: Awful customer service

After a few of my Milwaukee batteries would no longer hold a charge (after less than 6 months), I sent them back to the service center. They sent me the batteries back and said that they had tested OK. They won't even take a charge. Buy anything but Milwaukee cordless tools. Even Ryobi and Ridgid have better batteries than these.
