Being billed for service that has not been installed!!!

I am utterly disgusted with telkom.On the 10th of December 2018 I ordered a ADSL contract for my home and the same day I paid the R700 deposit.It has been almost 3 months and to this day no technician has been to my house to do the installation.When I phoned the first excuse was that the technician servicing my area is on leave.The second excuse was that my wife is not allowed to sign for the modem and range extender.After many emails and calls holding the line for hours no one can assist me!!!A dispute has been logged and every day I get the same answer that it takes 7 to 14 working days!!!Telkom it has been almost 3 months.You are billing me for services that I don’t even have!And your orders department expects me to pay R2691.81 and then they can send out a technician?!Billing department told me they will remove the amount displayed on my account until my service has been installed but yet the amount still reflects on my account.I do not understand how this is possible.It is the most pathetic service I have ever received.My usage displays 0 but I am being billed.According to technical the line has been installed.Can someone please get this sorted out asap as I work out of the country and want this sorted out before I leave for work.My order number is ********** 65A, my service number is ********** 20.
