Terrible Customer Service

I phoned the vodashop this morning to confirm whether they have the exact phones I want to upgrade to. The lady confirmed that they have the exact model and colour, and took down my details. She informed me that they are closing at 17h00 and I told her I will be there at 16h30. She said that she will have everything ready for us to sign and pick up the phones. Upon arrival at 16h15 I see they have already closed the doors. I speak to the unfriendly staff hanging around in front of the door who sends me to the vodacom4me store. Needless to say they dont have stock. So I go back to the store to explain that I spoke to someone who said she will assist me. After speaking to the manager they let me in. Now the lady tells me they dont have the colour phone I want. After yet again explaining that I already spoke to someone they magically get stock. Nowthey casually inform me that I have to walk across the mall to go draw cash as they are already offline. Then they wouldnt let the lady in who needs to sign for the contracts. Terrible customer service and this after I phoned in advance so they can prepare everything. So I left without the upgrade and very disgusted.
