Tired of doing the run around

I have ordered a contract from Telkom Mobile & I was told that it was pre-approved & once I was debited that would mean I was approved I could call & take the [package & phone I wanted. Before accepting delivery I called & I was told by Nosipho that I would be on a 1GB package with 100mins to any network. Once received, I confirmed when I was doing a sim swap and I was told that this was a 2GB Package. I called numerous times & I was told that it was being changed then when I spoke to Nonjabulo she asked me to return the device & she created a new order for me. and it would be delivered two days after the device was collected. I have followed up and there is no response. I am so tired of speaking to so many people & no one can help. The store sent an e-mail to the managers & still no response. I have also already been debited & I have no device or confirmation of the device or sim. This is not acceptable.
