Vodacom V and A Waterfront - do not trust them check every deal

Vodacom Store V and A Waterfront and Vodacom Insurance supp**** me the wrong device - it took weeks to get to speak to anyone as the store was closed for renovation. Then the two weeks in a row I went in store they said they will raise it with the insurance the third week I went in they had still not done so then they said they waiting for a recording where the Vodacom insurance advised them to issue me the Iphine 14 which was not teh case- yet now since I have used the devise - what else was I meant to do now they do not want to sort it out., It is clear on the voice message that the store is at fault.
