Terrible service from Telkom

I have been battling for months with Telkom to restore my ADSL line. I am working from home and my Grade 4 daughter cannot log into any online lessons because the line is so unstable. I'm supposed to have a 200 mbps line which runs at 30-50 mbps. I have logged countless faults which just gets closed every time with no resolution. I'm told my area is too small to get fibre and there's no space on their tower to switch me over to LTE. I have sent emails as well but hardly get a response. I am at my wits end as I cannot provide a proper service to my employer and my daughter is falling behind with school work. Please HELP!
