Paid for cellphone , but no delivery or feedback

I ordered a Iphone 6 off Telkom's website and I received a message that that I have been provisionally approved and that I must ensure that I have the finds in my account within the next 3 days . The monies were deducted off my account on the 14th October 2015 . I have since then tried to reach the call centre on 081182 who told me to contact 10213 . I have spent 45 minutes each time I have called just holding on for someone to assist . No one answers the phone . I have called Telkom Benoni on *** .NO ANSWER . Telkom Boksburg on *** NO ANSWER ! . I don't know what to do anymore !
