For Uncapped Internet, you may have 2 other options (Pure DSL and Fixed LTE) besides Fiber available to you. But, you'll need to check your coverage first to confirm whether your area is covered for either of those services. Please visit Afrihost.com and go to the "DSL" heading. Under this heading select "Pure DSL Deals". This will take you to the page where you enter the address you want internet for. From here, you'll be able to see if you are able to get Pure DSL or LTE and the packages available to you.
Hope you find a solution that meets your needs.
