I contacted them for an serious gas leak which was an emergency. I was alone with my three year old baby and didn't know what to do. The office staff calmed me down and asked about the gas cooktop stove. She quickly told me what to switch off and do things until the plumber come. Her advice was effective and the smell started to decrease. The plumber came within 30 min and I was able to breathe properly. He fixed the gas line and advised me the do's and don't when using the gas cooktop stove. This incident was the worst experience in my life but this company saved me. They are worth for my money!
