Bad Service

So sick and tired of Telkom that i will never recommend them to family or friends when you phone customer care centre the put you on hold and if you reach a consultant the transfer you from one person to another and if you ask to speak to a supervisor they cut you off completely first they sell me a 10mbps line for 2 years am paying for a 10mbps line only to find out recently that the area am living in can only take a 4mbps line the down grade you without your knowing i have been struggling for the past month with Internet and if you phone telkom they tell me that am on a 2mbps line i have tried to upgrade to a 4mbps line with no luck the one person tells you one thing and the other tells you another thing your ref nr means nothing they dont log your calls am beyond frustrated with no result i have laid complaints with telkom and still no luck don't know why i bother paying for services that i cant use been trying for weeks to just get upgrade to a 4mbps line
