'We will call you back' - still waiting

I upgraded my cellphone contract on 14 Jan 2019 over the phone. The package price, inclusions, device type, colour, etc. was confirmed and captured by consultant Anna Manickum. The call was then transferred to Senzo who second confirmed the information. About a week later only the sim card was delivered without the device. I called the upgrades department on 22 Jan 2019 and spoke to Zandile Ndlovu and was told that a 'sim only deal' was captured instead of 'with a device' and an investigation will be carried out where the call needs to be listened to, to establish what was agreed on. I never received a call back to give me an update. I have been calling almost daily to get a response and I am still being told that it is being investigated. No courtesy to even give me a progress update. I keep getting told 'someone will call you back', not sure if this will ever happen.

Seeing at the error was on Mondo's side (Awards Co), I should get some compensation for the inconvenience. I am now paying for a device contract where I do not even have the device.
