Telkom do not answer there calls!

I have tried calling Telkom today on 10210 and 10213 and 10217 and after holding for 17minutes+ they answer the call and keep quite and do not speak.<br> This happened numerous times and I can hear people talking in the back ground so it is not a mic issue.<br> This is absolutely unacceptable service from them.<br> <br> I wish to upgrade my package with them and then get faced with this service.<br> I got through once and was informed that they would call me back and no one ever did so I tried to call them back and again they answer and do not speak!!!<br> <br> What do I do now?<br> Calling and spending $$$ on a call to hold and not have any joy is really not how to treat a customer Telkom!
