No delivery of a device I app**** for 3weeks ago.

I had app**** for a device from Telkom online store 3 weeks go. After a agent call me and finished the application over the phone, I received a sms telling me I have pre qualified and they took money from my account. Ever since then I have not heard anything from them. And they said delivery takes 5 to 7 working days. However, its a total of 3 weeks now waiting. When I try calling them, I am put on hold for over 15 minutes. When I send them messages on their Facebook page, they keep saying they will let their mobile team know however, nothing ever happens. I have even sent a email over a week ago. And I am yet to receive communications from them.
