No response from manager and staff

Good day<br> <br> I ordered my upgrade in the Springs Vodacom store, but they advised me that delivery would take over a week.<br> They then suggested that i go though the Vodacom headoffice which i did about 3 weeks ago. I then called Vodacom last week Monday 22nd of June to find out what is happening. I was then told that the stock gets delivered on the last Friday of every month. Then on Sunday the 28th of June i received a call confirming that my phone would be delivered on Tuesday the 30th of June. I then called on Tuesday to make sure that it was delivered on time to ensure i was still at work as i had a meeting to go to at 2pm. They then proceeded to tell me that they dont have stock and they have no record of the call from Sunday!!! I think this is totally unacceptable as there is no communication from them to the client. If i didn't phone my clients regularly to update them of the orders i would be fired from my job. I have spoken to the manager twice and he has promised to get back to me regarding this manager. I am still waiting.
