ACT Fibernet — poor speed and customer care service

Address:	Hyderabad, Telangana, 500081
Website:	actcorp.in

The connection gets interrupt most of the time and they dont address the issue on time. They say it takes 24hrs to fix it all the time.
I want to disconnect the connection but they haven't provided any option on either their website or app.
The chat support is automated. It either allows you to enter your problem nor it provides an option for info on disconnecting.
Customer care service is poor. It takes around 15 mins to connect.
