Worst service by jio air fiber with very very slow speed

I have been facing problem with my Jio Air Fiber connection by getting very slow speed of internet as of 1 or 2 mbps since installation date 24 Feb 2024. My Jio fixed voice number is 01135902894 and my registered mobile number on my name Ashish Kumar Mishra. Many times I’ve complained regarding this very slow speed but till the date I am facing same problem. Jio technicians Mr. Naveen and Mr. Kamal have visited many times to resolve this issue but they are completely incapable to resolve this issue. When technician visit scheduled by Jio customer care on my complaint then Mr. Naveen says that Kamal will go to visit my place and Kamal says that Mr. Naveen will go for the same. I am really very very disappointed by Jio Air Fiber service because since last 5 months I am wasting my money for your service but Jio Air Fiber is the worst. Reference to my Service Request Number SR00001ZJV6M. Kindly either resolve the issue at the earliest or refund my money for which Jio Air Fiber has been failed to give the service to me.
