I rely heavily on my internet for business, and I have been having slow speeds since early in the morning. I called Surf4Life five times with no help; they tried to fix the speeds. It picks up, then drops again. Someone gave me contact information for this agent by the name of Tshifhiwa. He helped fix the issue and taught me a bit about how IP addresses work. Keep it up. Thank you.
