Apex Services India — cheated on name of ro service

I get a pathetic service from your RO customer service center and the technician named "Jitender" Mob: No: ([protected]). I made an RO service request call from "https://kent-ro.service-center.online/" via Mobil No given on this Site.
A lady name - "Jyoti Sharma" was on the line who arranged an appointment for Sunday Morning.
A technician came in the Afternoon at around 12:30 PM.

Technician Incident:
He asked me to change the membrane directly without even checking the TDS value of RO. Once I agreed to his wrong deed as being a consumer i was not aware of the adaptable TDS value range. Then I insisted him to check the TDS value as i read from google the Actual and adaptable TDS range value. It was found that value lies in the adaptable Range. Even then the technician was arguing and insisting on changing the Membrane filter, But I denied and asked him to replace the PreFilter only. He changed the PreFilter but after the operation waster started leaking out in a pressurised flow from the Filter. he opened the filter put around a tape layer on the internal rubber grip. At that point of time, the water leakage is not clearly visible. He charger Visiting Charges + PreFilter Charges (Rs 300 + Rs 350 = Rs 650 ).
After 30 minutes only when I checked, the water leakage was still present. I called up the Technician (Jitender) he responded in a very Rude Manner, Also have a recording of the same in the phone, and asked me to call again the Head Office(Jyoti Sharma).
Customer Care Executive Incident:
I called as per above suggested Jyoti asked me about what amount he has taken from and me and said will revert back to me in while. I again called her in about 1 hr later but again she asked only about the amount I gave, I asked her to connect me with some higher authority but she denied doing so in a rude manner (recording in phone saved), Then she put my number on Blacklist mode. Hope no need to explain how to check if someone has blacklisted your number or not. I made several calls again to Technician and Jyoti with different numbers but one by they kept on Blocking the numbers. Still, my RO Problem has not been resolved, I don't understand such behavior pathetic behavior of your team.

I assure you guys, Legal actions will be taken against you if my complaint is not resolved on priority and I demand clarification of such behavior from your team.

For Proof, If need I will upload the Conversations on Social Media as well.
