My service request no [protected] . Amc contract done on date 28 dec 2019 . No service done due to lockdown, service technician came on 27 sept 2020 to replace all cartridge, he cheated me by installing a used 2 years old RO membrane cartridge. He had opened the sealed cartridge bag at his shop, removed the new RO membrane cartridge and replaced with a used RO membrane cartridge . Several times i called eureka forbes aqua guard but no response they are shielding the culprit technician, aqua guard call center person one day telling me customers should check weather the bag is sealed or not, yes he is correct dont trust the technician from aqua guard, he will cheat you, in current pandemic situation he expected that me a senior citizen to check the bag weather its intact . Aqua guard should answer me weather they will not replace the old installed ro cartridge given by their technician thus cheating me .
