Why should I do business with you?

In May 2015 my husband and I went to Telkom wonderpark to apply for a business line. We took a SmartOffice Basic contract and completed the application forms. The line was finally installed after three weeks of waiting. Then our problems started. First the technician did not know that the application was for an ADSL line so obviously he did not bring the modem and the ****le that came with the package. The next day he came with the modem but no ****le. We went to the wonderpark branch and we were told they were out of stock and they will order a ****le which will be delivered. Three months later, still no ****le has been delivered. Today I contacted customer service to find out what was going on only to be told that I am not getting any ****le because the application that was captured was for a different package. What the hell? Now this explains why my bill has been so high. Since I had this line I have been having one problem after another. Debit order was not captured and now this as well? Could someone sort this out as soon as possible. I need answers....
