Telkom LTE COMPLAINT

I registered for the telkom LTE special at R599 per month on the 3/10/2015 ticket number ***. For over a week I never heard back from telkom, then I was contacted by Mrs Balungile Ngcobo who went through the contract with me telephonically and I agreed to everything including my my banking details and was told my LTE modem was on its way. After waiting a week we still had not received the LTE modem so I sent an e-mail to Mrs Balungile who called me telephonically again to inform me that I should take a demo, to which I retorted I do not want a demo, I know it will work in my street now please submit all the information that I have given you over a week ago. A few days have passed and nothing has happened. In the past two days I have sent her 3 e-mails asking her to advise if she has submitted my details to which I have received a response, I've tried calling the contact centers and the people have no clue what is going on and don't know how to escalate this problem! I would just like the details I gave Balungile Ngcobo to be submitted and to receive the LTE modem urgently as this has already taken far too long!!
