RO Spare Parts - RO Point

They replaced all purifier tubes but after that ro started leaking water continously from waste tube. We contacted the person after a few days but the representative was on leave. When he came I showed him the issue and told this happened after he opened and replaced the device. But instead of accepting the mistake he started arguing that I must have done something with the ro. Now we have to pay him more

I am an old customer of ro point, they are very nice peoples and service providers
