Exide Industries — complaint against service engineer ajaz ahmad

Sir,
I had booked a complaint (Complaint number njka00027937v543) on 17.8.2018 regarding low back up of exide inverter it500 battery. Service engineer of exide company namly ajaz ahmad (Cell no [protected]) visited my house to check the battery in very unprofessional manner. He told me low backup is due to low gravity of electrolyte, i asked him to check the gravity with hydrometer properly but he dont had hydrometer with him. He told me that he will come tomorrow with hydrometer but he didnt. He asked me for the purchase bill which i provided him innocently with out knowing that he will deceive me. On 25.8.2018 i called the exide toll free number to check the status of complaint but to my surprise they told me that complaint was closed by service engineer. That guy ajaz ahmad, so called service engineer of your company is un0ofessional and fraud, he make fool of innocent customers. I request you that strict action be initiated against that man
