Telkom ADSL - works for 1 or 2 hours every 24 hours

I have had the uncapped ADSL for close to a year now, paying R600 every month. The amount of days it actually works is shocking, and we are right next to a tower. I dont care what excuses you come up with, R600 per month for a product/service that works 30% of the time is absolutely ******* and ****************. I swore I would never go back to Telkom after my last ADSL 2 year stint, but i thought I will give them another chance with all the fibre service operators out now, I wish i never did because they cant offer the same product or service. They wont even contact me to see if they can come out and sort the problem out and make the product I purchase every month work the way its intended to.
