No response from Vodacom online division!

On Friday the 17th of November I preorder the long awaited iPhone X from my Vodacom online. I had received a confirmation email with a reference number stating that an agent will be in contact with me. Come Thursday, the 23rd of November- still no feedback! I phoned them and they said that someone will be in contact with me the following day. Friday morning, I tried to upgrade my contact with one of the specials that was running on the iPhone X. I again recieved an email with a reference number stating that the agents will be in contact with me. Come now Saturday morning still no response! I phone this morning to gain some insight into the situation only for the lady to tell me that they have no stock and that there was never an application for an upgrade only a request and I should wait for the agent to phone. She said that I cannot recieve the same contract anymore since it only app**** for yesterday! This is so upsetting because I had done ALL that I can do on my side and then I miss out on the specials due to their lack of response! I have been trying to get in contact with them since but I have been on hold for 30 mins TWICE and they don’t answer anymore. The Vodacom store can’t help me because it is the online division. I am so disappointed in this service and lack of communication! We pay over R3000 a month and have been loyal customers for years now. It’s things like this that makes me want to switch to other cellphone service providers! Vodacom, your service is appalling and I hope you fix it soon.
