Dear Sir, With all due respect, I am writing this letter with a complaint regarding your services. Since the past 4 months, the AC installed in my house has not been working properly. At the start, I was very pleased with the AC and your executive told me to buy a stabilizer for the AC .I bought that stabilizer still AC doesn't work properly, I request you to please replace the AC. This is my 3 rd complaint, I'm very disappointment of your services.
