Bad customer service on fiber installation

I have logged a call on the 30th of October that I was moving from one unit to another unit in my complex, I received an order and the Openserve contractor came and done the installation but Telkom cant connect me because they cant change a unit number 4 to a unit number 8, I am on a contract with Telkom for the fiber so I paid the monthly subscription for November and its the 15th of November without connectivity, every time I contact Telkom there is a new excuse, system off line is their favorite, I am fed up, I pay for a service that I don't receive, my next step will be to take them to the Ombudsman as they are actually *****ing my money and don't provide me with a service.
