Absolute disgusting service form Vodacom

On Friday Morning 11 September at 08.00 am I requested an online upgrade for my cell phone number ***. I was contacted by a lady that said she will be doing my upgrade telephonically. While doing my upgrade I checked with the lady when delivery will be done and that I require a cell phone that is in stock and I need a new handset asap. She ensured me that the phone I am requesting is in stock and that they will be delivering either Monday 14/09/2015 or 15/09/2015. After spending almost 15 minutes on the phone with her doing the upgrade I was phoned shortly thereafter by a very friendly gentleman that said he need to do my upgrade with me, I then told him I just did this upgrade with a lady 5 minutes ago. He told me that nothing was even loaded on the system !!!!!. I then spent another 15 minutes with this gentleman on the phone explaining my exact instructions to him. requested a Samsung S6 Edge 128gb (black sapphire) that I was ensured is in stock.I phoned the upgrade department numerous times and getting transferred all over the place to try and track when the delivery will be taking place. Still no ONE can tell me whats happening. Disgusting costumer Service!!!
