ACT Fibernet — have been continuously trying to get in touch with the customer care from 1 month

I'm located in bangalore and wish to disconnect from act. For the same i have been trying to get in touch via their app, but there's no option for disconnection. Instead it redirects me to unrelated faqs.
I have also contacted customer care and have tried all permutations and combinations to reach someone i can talk to, but i end up getting redirected to unrelated nonsense. I'm highly frustrated and disappointed and wish to have never gotten an act connection.
