Failure to deliver promised goods (cell phone)

Over a week ago, I got a phone call from Selldirect, offering me a contract for a Sony smartphone, minutes and data for R69 per month. She said someone would contact me shortly to arrange delivery of the phone. I got a follow-up call confirming that I would pay R90 admin fee at the end of November, and thereafter R69 per month. But to date no one has contacted me about delivery of the phone. On 29 November I got an sms from Selldirect saying R90 had been debited to my bank account, and giving a number to phone if I had queries. I have tried repeatedly to phone both their numbers, and sent an email on 1 December, asking when I would get my phone. The phone numbers both go to dial tone after ringing for some time, and no one has responded to my email.
