Yutiliti support failure

Worst customer service ever. Upgrade from a 200 line to a 500 line. no increase in speed ask them to please upgrade my line i think they forgot. Had usse their prefered speed test app with the 200 line had real speed of 128 now still 128. This attorney from them phone me after logging a support ticket. telling me the router is to high. although i can see it. Got on the ladder redo the test same result then it was because it is wifi. The 500 is just when you have a cable. They really are the kings of excuses'. No accountability. Well suppose that is the South Africa we live in now they fit right in.
