Waiting for delivery and call center not helping

I ordered the R99 special for March (5GB with the mobile router). The first debit order went off on the 30 Mar. I was told delivery would be 5-7 working days later. This past Friday would have been 7 working days. Still no device. Also, in last week I kept receiving emails saying that Telkom is trying to reach me. So I have been trying to phone the call center. Last week and again today I keep getting told I am in the wrong department and I must phone another number. Some consultants put me through and the rest say they cannot transfer me. Don't know how that works but ok. I have still not spoken to anyone that help me so I still don't know where the device is and I have already been debited! I even tried their online chat option to speak to a consultant and they said they would send the relevant department an email to call me. I gave them three different numbers that they could reach me on. I have still not received a phone call. This is such terrible service before I even get to be a proper member of Telkom that I feel like cancelling my contract before it even starts. Also, because I do not have a telkom number I pay each time I call!
