Its quite frustrating and sad to hear this. I went to their shop at IMM once.. I walk around in the shop for abt 15mins waiting for ppl to serve me. But no salesman came forward and talk to me. Didnt really wanna get it from there. Just that my frens were telling me how bad their service is. And I went there to try, true enuough. Mayb my age don't look like someone buying air con for my new house. But a walk-in customer is always an opportunity. You might wanna try AllBest. I went there a few times already. But haven't get anything from there. But my fren had just purchase a system 3 from them last month. They have already install their aircon and so far there isn't any complains from them about their service.
