NO SERVICE

I have been having problems with my business internet and Telkom has previously attended to this problem. Telkom then advised me to dedicate one line to the ADSL system. All I needed to do was send a written request to Telkom and they would then make the changes as requested. This I did on 22 September 2015. Up until today nothing. I have however received my latest Telkom account and their is an Unnecessary Call out fee of R912.00 added to this account. How can this be if they have still not sorted out the problem.<br> I still have very bad intermittent ADSL connectivity.
