Den Networks — network issue

Hi all,
This is about the network issues which i am facing almost every 3rd day. Den networks has degraded its services so much now a days. Firstly the network is quite costly compared to other networks. Secondly we face network issue alot, i am using 50mbps plan and still i am unable to use my wifi some times and the speed too slow. Also, the staff is not very cooperative. They don't answer your calls and leave it like nothing happened. They are not doing their job properly. As you can see in the screenshot also, while typing this message i am not getting any wifi signals

It's my sincere request to you all that please don't use den networks. It sucks
