Telkom internet fibre woes

Second week of May had my telkom fibre intalled at home, 28 of May i lost connection to the internet. Called them to log a fault and was informes technicians will give me a call when they come. A wek later i receive an invoive for services uses, called and explained and the consultant said i can only pay the invoive if i have used the services for 30 days so i need to wait for technical to fix the problem before i pay. Today i received another invoice and still no technicians has come and i still dont have the internet. Called them the whole day from technical to billing to sales and still no help. One consultant suggested i pay the amount and query it later, when one say they can send technicians to the house but i need to pay R1200. What kind of services is Telkom offering? Why are we being billed for services we are not suing?
