VDSL Problems

I am disgusted at the level of competence of such a huge organisation. I don't even think their agents are even fully trained and most probably just given a day course and then seated at a desk. the customer service if horrifying leave alone their capacity to problem solve . from their agents to their floor manager are clueless on what actually goes on . I have been trying to resolve an issue of mine for over a month which is of no fault of mine. All these agents don't speak with the same voice ,no clue as to what needs to be done regarding a query. You call Telkom spend 30 mins holding and another 30 mins trying to actually make them understand what you need , and they still get it wrong. upgraded from a 10mbs to a 20mbs line. Ever since the upgrade I have been having very slow internet speed. Calls have been logged with telkom, but everytime a call is logged an open serve help desk technician will call me and change my line sync speed. I am Paying for for a service i do not have. Last week telkom suspended my line because they are not willing to assist. My account is up to date and i pay extra every month. Last nite i have called the telkom help desk. Have tried to explain to the lady on the phone my problem. She did not want to hear anything and asked me to call back afer an hour. Still having the same problem.
