[Resolved]  Eureka Forbes — working condition water filter being broken by a fraud technician

In the name of aquaguard one technician from aquasure visited my place yesterday (03-jan-18) for water filter servicing. Even though we didn't make any request for servicing it was done from customer care. He opened the water filter and said filter needs to be changed and i have to pay rs350/- for service charge. I said i have amc from eureka forbes and showed him the receipt. He took the snapshot of the receipt and told me he will not do servicing as this is under amc and he will come back after vising the office. So he started assembling the parts of the filter. After fixed everything water started leaking and he said he doesn't have the parts and he will come back in the night around 8-8:30pm. I said we will not be able to drink water so do come back.
But he hasn't come back till now and he is not responding over phone the moment he recognizes my voice.
My question is how aquasure got to know all my details, i never share my water filter and other details to any third party agent except eureka forbes. This is a big scam going on by aquasure in the name of aquaguard and eureka forbes should take stern action to protect his customers.

Thanks
