First of all buying an aquaguard product is a grave mistake. If at all u have bought one , never pay for AMC (annual maintenance contract). Unless u have some hold, u cannot get them respond to ur problems.
Once u pay the money for 1 or 2 years, then it is your turn to chase them. Below is my experience.
Last year I was not AMC. I was able to get some amount of response from them upon repeated calls(usually more than 5 times and waiting for more than 20 days). But since the day I paid for AMC, they never attend to our complaints.
Never believe what the salesman (scoundrels) says.
