Paying for a non existing service

Since 19 march ive been working from home. Never had problems with my sim and connection but since working from home i was unable to work due to download speed being from 11pm till 6pm the following day either on 0.01mbps, i am lucky to get it on 0.1mbps. This is unacceptable as i pay for uncapped data with download speed of up to 10mbps as per all the ads. I never experienced even 1mbps since 19 march. This is unacceptable as i pay every month. My company even wanted to move over 500 workers to rain network in order to work from home and i could not recommend rain. I had to pay over r700 in data on other networks in the past 3 weeks in order for me to be able to work form home. I even bought a wifi router paid 1800 for it to still give the same download speed. The sim useless for me to work from home. Who is going to compensate me for all this money lost for something you advertise thats clearly not working. No response on emails sent since 21 march, on facebook they took 2 weeks to reply to only send me a rain speed test link asking if its better.... No it is not, i sent numerous screenshots via face book at different times of the day and night to show its still the same... No response on that either... How is this treating customers fairly as no one can provide a service advertised. Its ****************. Paying for a service i do not receive.
