Kindly PM me so that I can test your account myself.
I have had no joy since I moved to Openweb... I am throttled almost all the time and can barely browse and can never download anything more than a few MB. I mailed support a good few times, they "reset" my account, gave me alternative log in details, etc. but it's so slow and frustrating I rather use my phone and 3G/H+ for browsing, e-mails and even youtube.
I have now cancelled as they can't seem to assist me, busy looking at other isps trying to decide where to move. I left MWEB because they throttled me for abuse (I only use a laptop so if and when I download it's only in the evening), tried Openweb and its even worse than when MWEB was squeezing my traffic through a pin hole.
Trying to decide on Afrihost or Cybersmart or if I should just go back to Telkom....
