Telkom issues

Last December we upgraded our account to telkom unlimited 10mb which also comes with a telkom 2gb WiFi integrated sim card, to this day the wifi sim card does not work to this day, I've been to the telkom store and I've phoned tech support but still no help, I eventually got tired of trying and just forgot about the sim card, now recently my account was suspended, I did however pay the amount and phoned the account department and asked to be reinstated, they did reinstate me but my Internet was still not working, they then transferred me to the tech department, I've spoken to 3 consultants 2 of them did a telkom username password reset but still the Internet is not working, I explained this to the consultant she then told me to take my modem in for testing the fault is with the modem, I then went to the telkom store, I waited in line for about 30min, when I finally got to speak to a consultant she told me that this store does not have a technical platform and that they cannot do testing, they told me to book the modem in but it will take a few days maybe even a week, I said I did not want that so I went to go buy a new modem because i thought the fault is with the modem, so I returned home with my new modem set it up etc but still it could not connect to the Internet, I then did a telkom username password reset via sms, i then received this sms, ''Your cellphone number is linked to more than one Telkom Internet account. For further assistance please contact 10210. Regards, Telkom Internet" . Telkom is pathetic when it comes to fixing problems they make more problems then fix any, everyone has an issue with telkom.
