Uncapped, with an asterisk to cover themselves

What does uncapped mean? does it mean from the 18th of the Month they reduce my speed to almost unworkable levels? Apparently it is because I used to much data and am affecting the entire country as per Telkom. I am Paying for uncapped at 2MB, I DO NOT GIVE A **** IF YOU PUT AN ASTERISK NEXT TO THE WORD UNCAPPED. Telkom are dirty rotten ********* who are slowing South Africa's progress. And their call center doesn't even work. I want somebody to call me and restore my internet back to the correct speed. I will take Telkom on for False advertising and deception. Oh, and they also owe me two weeks of credit as my line was down for 2 weeks at the end of March.
