No feedback on complaint of no delivery

So a week ago I complained that I am still waiting for my Unisa study material to be delivered. It eas sent out according to your waybill on the 25th of July. It is 2 months now that I am waiting. No one has been in touch with me to explain why there is such an incredible delay. And no one has even bothered to respond on my complaint. This leaves me no choice but to report you to the ombudsman. Since your lack of service is laughable. I really hope Unisa takes note of all the student complaints and starts using a different courier. We are 2 weeks away from exams and you are still sitting with the material I need to prepare. I will be failing my exams because of you. Great job guys really. My unisa study number is ********** 0 if you would like to at least get back to me with an explanation. I've also attached a screen shot of your waybill
