Disappointed

I am extremely disappointed with Telkom and the service that I have received. My account has been debited however I haven't received my phone. The supervisor was supposed to call me back today which never happened. I ordered a phone and I changed the phone prior to delivery and acceptance of contract however they delivered the phone that I didn't want. They took the wrong phone back last week and haven't delivered the new phone. I spoke to an agent today who advised that I am using the old phone and it is active, how's this possible when the phone was collected last week. Nobody is helping me and I will be seeking legal advice if this isn't sorted out this weekend
