Lacking of communication

Did an upgrade on my contract on the 5th of May 2022. Received confirmation sms that upgrade was successful and received my agreement via email, with the promise that new phone would be delivered within 3-7 workdays. Now a week later, I have not heard anything from courier company nor have I received the phone. Phoned Cell C customer care 5 times, NO ONE can answer a simple question - Has the phone been dispatched, is there stock issues with this phone, because if so, no consultant mentioned it to me. Unfortunately I have to work with Cell C direct, as we do not have an Cell C store. I want to know, has the phone been dispatched - when can I expect it to be delivered - is there a tracking number for the parcel - and what is going on with my upgrade!!!!!!I've been with Cell C for 10years +......and is this seriously the service you give you're long standing clients? Please can I have answers, as calling call centre is of no help, you go threw all the red tape, being put through from one person, department and NO ONE can assist you.
