For capped data, Afrihost is still the number one choice. Great work Gian and the AH team.
Now you need to focus on getting your uncapped packages in line with those of MWEB. I'd much rather support AH who revolutionised the ADSL industry in RSA. I wouldn't mind paying R899 to AH for an all-inclusive 4mbps uncapped line, instead of to MWEB. However, your FUP and service (network, quality, speeds, latency, redundancy) needs to be comparable or better than MWEB's.
You will win over a lot of customers if you can do this.
