Same, My progression (MWEB since BigBlackBox days -> Afrihost Business from 2012 -> TI from end 2013 to now -> Afrihost Business)
I'd say the worst thing about Telkom is the lack of presence on this forum. They are unwilling to admit that their service levels were bad, and they did nothing to help calm the nerves of the consumer down with public statements or anything.
AH and Mweb I'd have to say are ok but the AUP on Mweb rubs me the wrong way so I wont be going back to them
My expirience with Telkom has been the past 3 months, In those 3 months I have had maybe 5 flawless days of internet. Day 1 of AH business today and it is amazing.
