ADSL misleading

Good day,<br> <br> I have a complaint with Telkom and would like to have some assistance. Two to three months ago, I called the Telkom call centre for an application for and adsl line at my home. The guy that assisted me over the phone were very helpful and the application was done. He informed me that there is an installation fee that the system shows but then told me that he talked to his supervisor and they will override the system so that I don't have to pay for the installation as this was my first application. He told me that with first installations there is no installation fee. The application went through and he informed me that no fees are payable for the installation. Just to be surprised a month ago that the amount for the installation fees were on the invoice. I then contacted Telkom explaining it to them and a dispute was opened, just to find out it was closed and rejected without any reason. I then phoned again to ask what is going on and a lady informed me that she will send an email to the person that dealt with the dispute to send me an e-mail or call with information to my dispute. Till today I am still waiting and received an sms saying my line will be cut if I dont pay
