[Resolved]  Eureka Forbes — Sales person changed membrane from hight to low

Hello, We bought Eureka Forbes Reviva Water purifier. Sales person from eureka forbes which bring that machine change our original High TDS membrane from Low TDS membrane and that too too year old membrane. After only 4 months water quality became so bad it is hardly drinkable. After one month calling they sent some service person who told us that sales team made us fool by fitting 2 year old membrane in out new aqua guard filter and keeping our new one. Also we come to know from source that they have sale us new filter over 2500 more costly from original price.

Now when I am calling them to change membrane they are saying they wont and not picking up phone any more can some one look into this matter please?
