Been waiting for over 5 months and counting

I have been waiting for over 5 months for Telkom to install an ADSL line. There is a cable issue, but there is a communication problem between Telkom and their cable department. A technician has been sent to our premises 5 times and every time they get there, it is a Telkom technician to install the line and not an Openserve technician to sort out the cabling issue. It does not help for me to contact 10213 or 10210 because the consultants have absolutely NO idea how to solve this issue. I am SO tired of raising my blood pressure on the damn poor service that you offer. PLEASE can you get the right person from Telkom/Openserve to contact me to arrange for installation
