Cannot get phone or cancel contract application

On the 27th of February I app**** for a new contract online and I was told I would receive it within the next week, a week went by and I called Vodacom and I was told it’s on back order as they out of stock. Today I called to ask them to rather change the phone and take a contract with the iPhone Xr instead of the iPhone SE which is out of stock and I was told the person who had helped me with the application would call me back. That did not happen, so I have now called them on ***4 to cancel the whole application and a lady called Lynette (sp) said I need to call *** but I could not get any help as it requires a Vodacom number which I do not have as this was an application for a new contract. I called ***4 and spoke to Lynette again and now she says she can’t assist me because the system is down. I am not even a Vodacom customer yet but already the service I’m receiving is so poor, thanks but no thanks I will rather go to another service provider or buy the phone cash because this is not the service I was expecting from Vodacom. Please just cancel that application because I will NOT accept the phone.
