less than half of my speed but want me to pay full amount of bill payment?

Since June,

I am having less than half of speed and even sometimes 1/4 speed of gigabit pro which I pay for

but it is really hard to contact to customer service due to Covid19.

And there was 2 times of service outage and one of them lasted more than 24 hrs recently.

Should I get discount or credit for this?
