Not getting what we pay for - internet

I'm having major problems with Telkom. I pay for a signal that keeps going away and I want to cancel this contract. I don't feel like i should pay a penalty because I'm leaving because of lack of service. Lastnight i set up my laptop to download stuff from 12-7 when i woke up it barely downloaded anything. This has never happened in the past. Nothing is wrong with my device in the day why doesn't it work at night. When i check the data. It shows that data is gone yet i can see that the stuff didnt finish downloading. I can't even stream online. What a joke? Someone needs to check what's wrong.

When you type a complaint, the social media team is either not working at that moment or they are 'recharging' - so, now I have to go through my day remembering that i still need to resend my complaint because I sent it at an inconvenient time and I should know that they won't respond unless I resend. Then when I do, they ask details and when you send it communication stops unless you remember to follow up day after day.

I really want to leave Telkom. But I have 1 year of this horror left.
