Address/Line clearance

I moved into a house 1 December 2022. There was a fiber so I placed an order through WebAfrica (as I had an account with them). Was told that they can't place an order as there already is a line. I explained I am the new tennant and do not know where the previous tennant is. Provided WebAfrica with documents stating when I took ownership of the house. I was told Vumatel needed to clear the address/line so that it can become available and have the order placed. It is now March 2023 and still being told the same order.

I thought the issue was with WebAfrica then tried a different SP.

I then placed an order with Afrihost in December and had to deal with the same situation.

Both SPs can't place the order as it still needs to be cleared by Vumatel.
