We had a head restrung and were told to pick up on Saturday. They told me that they were open till 4. We left our plans earlier to get there at 3. Nobody was around. Other customers were waiting outside as well. When I called on Monday and expressed my disappointment, they claimed they would help us out. My wife went to pick the head up and as expected, they did nothing for the earlier inconvenience!! The work is good, but the customer service is bad!
