From pillar to post

I have a couple of Telkom issues, both business and personal. I call one department, e.g. Accounts, sorry they cant help I have to chat to Sales. I am SOOO sick and tired of calling. I also went into a branch, they cant help with my Account, and then i sit calling and the whole vicious cycle continues. Why cant ONE department take accountability and help. With business mobile its even worst, still having issues a month later.
