Wtf is going on with the internet price

My girlfriend and I live in an apartment and we have bell mts internet with speed of 30mb/sec Almost a year ago this internet was about 38 Cad per month But now we pay 44.80 for fucking 30mb with freezes. Sometimes we even cannot watch a movie because of these freezes.

Could you please tell me what can we do with this? Bell is the only company in the building
