Poor Workmanship

This company came to replace my broken gas geyser. I have never seen such a poor workmanship in my entire life. They have connect my new geyser with braised flex water pipe which looks terrible and I'm staying in a complex. The flex pipe is also going to affect the water pressure on the gas geyser. They were supposed to change the copper pipe and fittings to fit the new geyser. They didn't even clean up when they were finished with the installation. The owner didn't even came out to inspect the installation. I don't think he will come. Avoid this company as far as possible.
