Telkom demands monies on account billings for no service lines on contracts!!!!!!!

Me and my wife signed up for a telkom adsl contract in Feb 2017 outside trade center in Pta east on one of those gazebo tent promo's they doing....they announced and assured us we will get a line within 14 working days, 4 months later they rock up at our home with no appointment scheduled , luckily for them and unluckily for us... my wife was home that day!(We very much regret the fact that she was home now!!) They went on installing the line into our studyroom. The Technician told my wife we should go in to the nearest Telkom shop to go and activate the line and sign the final contract and get the Hardware to use the line(Router ect which is part of the deal ) I went in as soon as I could get a afternoon off from work to go and do this needed to get the line activated only to find out that the line was already activated and they billed me for line usage already ...I had no router to use anything on the package and ask them for my signed contract , They logged a dispute on this and asked accounting and billing to send me my Contract signed on the street according to the that was the contract(piece of paper)A month went by , nothing came no router , contract !!!! We are now in Oct and 4 x urgent disputes and quarries has been logged...I have still to get the line sorted and still waiting for my signed contract...my router came on the 20 th of September and when I phoned them again and asked for the password ect to start using the internet now that i have the router they told me the line is suspended due to outstanding billing?????So Telkom has been charging me from May till now for rental on a line I couldn't use because they were out of stock on the hardware as they told me!!! This is the battles we need to face every day and still they take our hard working monies for no delivery on service ....do as they please...No one is phoning me back , and its been again 2 weeks since they said this matter has been escalated to an upper level for urgent attention .....What ells can we do?????This will go on for a year or more while the billing on my name will pile up!!!
