Adsl down

As per my previous report. My Adsl went down eventually got a techi out who diagnosed my modem as broken. Took modem in , no stock, left modem there as I wanted to cancel. Another two weeks went by got a call from technical assistance who help me brilliantly, it took over two hours to fix. So now I still don't have a telkom modem so cant use my usb ****le that came with it, and I still get charged for unnecessary call out, wasnt it your people who said the modem is broken although my network ran flawlessly from it and only had a problem with the ADSL. How can it be an unnecessary call out. And how am I going to get my modem back.( This was left at the Springs branch)
