I ordered wireless keyboard K350 and wireless trackball. The package arrived but had been damaged and the tape that ran the length of the box had split open and 3 pieces of tape had been put across the top. The keyboard was there but the trackball wasn't. Logitech won't do anything about it without pictures of what i received. I don't have a camera, so that isn't possible. They refuse to do anything about it. They have no customer service department, it seems. I talked to 4 different men and they all just kept saying they had to have a picture. The 4th guy refused to put me through to a supervisor. He kept calling me ma'am and he never got excited but it was plain that he had no intention of doing anything to help me. Just finding a phone # for them was a major ordeal. Whoever heard of a company not having customer service people to help you that you could reach BY PHONE!
