NO SERVICE

Good Day

I have a 10mb uncapped line at home for personal use. For the past week I have had extremely high ping. Now I pay a hefty amount each month for a service that telkom is not delivering. SO for what am I actually paying for? If I had to stop paying and brake contract my linbe will be blocked and I will most probably be black listed. But if telkom does not deliver the service promised, it is my problem?

I have gathered the necessary information and evidence and if telkom does not respond back to me by 16/03/2018 I will not pay my account and will get a different service provider.
