IMO Neotel is a failure.
They were handed a golden opportunity to enter the marketplace as official competition to Telkom, and then decided to go the wireless route.
That in itself was perhaps not such a bad move considering the cost of cable infrastructure.
However they by no means came up with packages that would really entice me as a consumer to make use of their services.
Add to that a flood of online complaints related to their customer service and technical support, and you have a recipe for failure.
Unless Neotel can come up with good marketing, amazing deals and great customer service, personally I wouldn't touch them.
