Aquafresh Ro — false claims by the company, feel cheated

I had purchased aquafresh nexus swift from their office in dwarka in may 2018. I was told by them that they have a service centre in sector 15, noida and they will be providing 1 year amc on the system.
They are very poor in servicing the system and they do not have any service centre in noida.
On 16 nov 2018, i had complained to them that the system is not filtering the water. Almost 1 month has passed but nobody has come to repair it or even attend to it. I had to call someone else to get it repaired and pay for the solenoid valve.
I feel greatly cheated by the company. Even their manager vijay sharma did not bother to attend the complaint.
