Vi Furnishings Private Limited - Network issue

I live near maruti kunj in gurugram, am facing network issue for an year, am tired of this, it never work properly. Due to this I fail to hear or convey my msg on call many times nd same is with data it take a lot time to download a single picture nd most of the time I have to use hotspot from others. I will switch my network into jio or airtel if my prblm will not be taken seriously.
