(i-nova) Eureka fobes
Product not working

I bought a product of eureka fobes water purifier model-i-nova

last year.product was working properly. Some of the salesman of the above company asked to change the parts i.e filters because they run for six month only after that they are of no use. i phoned to service office of eureca fobes panipat.they changed the filters but from that day product is continusely giving problems that is water continously comes from the m/c when m/c is off. the service man of the company has changed the auto valve of the product but still problem is there.after continously phoning to the service office no one is bother about the consumer problem.
