Very dissapointed

I ordered a device on Black Friday online. Someone called me the Saturday to confirm details and order. An amount was taken from my bank account as verification on the 30/11/2015. Delivery apparently takes 5-7 days for the device i have still not received it. I called the call center and no answer for 25 mins. I then used live chat and promised a call back from manager then nothing. I called again the next day and they said they can assist as they dont know what is wrong so the person who made the order will call me - no one called. Then i called yesterday 09/12/2015, and promised a call back still nothing. I called again today and promised a call back still nothing. All i want to know is when do i get my phone. This is unacceptable service from Telkom, i did not even start my contract and i am already unhappy. Someone please sort this mess out.
