Reliance Jio Infocomm — Jio Fiber Internet speed is low

I am getting 16 Mbps speed on my jio fiber. My plan is of 150 Mbps. I called their toll free number yesterday and their support lady told me to remove all my devices and stand near the wifi router. I got 35 Mbps on 4g and 89 Mbps on 5g. She told me that I have a healthy speed. I told her to file a complaint because this speed is not acceptable.She told me this report will go to her team but no one contacted me yet. Jio is the worst fiber connection company, resolve my issue or I will see you in the consumer court.
