Faulty ADSL business line for 4 weeks

My adsl line *** has been faulty from the end of Julf, 2 technicians have been to site and have not managed to rectify it, yet every day they manage to close the fault. I have had to buy 3g bundles worth 499 every 2 days! this has menat my telkom bills has soared to above 10 000!!!! No one is taking responsibility and this has hampered my business as i run an internet cafe, what kind of internet cafe can i run without the internet!!! Telkom you need to sort this or else you will lose a customer for life!
