Bribed and let down

Hello, I moved homes 2 months ago ans had my telkom adsl line moved from the old place to the new place. My line went down 8 days ago, and they dispatched a technician to fix it. They fixed it, but have put the line back at my old addres!! I've spoken to 10, yes ten agents who have not been able to help me. They won't change my details so on their system my address is still the previous one. They tell me my current address doesn't exist, even though they came here to install my line. I've tried to speak to managers with no luck, I've even had a technician down the road try bribe me for R500. I didn't have cash so he said he can't help me. What do I do :( I need this line for my business, I've lost out on 8 days worth of money. This is beyond ridiculous. Please help.
