ACT Fibernet — Frequent disconnection and refund not clear

I am a regular customer from past few years and have been using paying amount asked by act. From past few months, i am facing issue with the internet and it is not fixed yet. I raise complaint and some one comes and fixes it after some time again it will stop working.
Multiple executives/service engineers had come to our premises in this pandemic times and with having senior citizens and also children in the home, i do not want to take chances for the same.

After 100’s of complaint i have decided to disconnect the connection.in this regard i request to refund my amount for past few months where i have lost the connection and also till feb 2021. Request to reply at the earliest and settle my payments as soon as possible.

I am not getting proper response.

Thanks
