Excessive application turnaround time, no feedback

I app**** for an LTE package & smart TV on Sun 09/05/2015. The consultant said the application would take up to 3 working days. I emailed my bank statement the next day. Only after several follow-up emails did the agent acknowledge receipt of the statement. By Fri 15/05/2015, I had not received any further update despite sending him follow-up emails. I tried calling the phone number listed for the Eastgate Telkom Direct shop, but it keeps going to a voice-mail which states that 'the inbox is full'. So I tried calling the agent's manager directly on the number he had sent to me, ***. He told me that the he would call the agent and then give me feedback. He never called back. After more email follow-ups the next week, I got an email from the agent on Wed 20/05/2015 asking for my TV license, which I sent within 2 - 3 hrs. The next day I got an email asking for a R3,000 deposit if taking the TV but no deposit if there is no TV. I then cancelled the TV and asked for the LTE package only. I never received any response from then until today. I have emailed both the agent and the manager and left several messages on the manager's number but but got no response as of 11/06/2015.
