Vodacom After Sales Appalling

I received a call from the sales department as I was due for an upgrade we did the necessary via telephone my phone was due to be delivered on the 25th. When I checked my wabill no on the day I saw that a note was added saying that the driver was hijacked. I received no call from Vodacom explaining what the procedure would be or the tat for investigation or anything just silence. I called their after sales and spoke to Gugu who said that it was still under investigation, I asked if I could cancel the order as IL rather go into the store, she confirmed she would call me back to confirm but did not. I called again a few days later and after being trf a numerous amount of times, I asked to speak to a manager and was transferred to a Team Leader, Curtis Green. Who was supposed to get the matter escalated because what Gugu failed to mention was that you can't cancel an order until investigation is complete. Curtis called me back on the day to say that he would talk to Vodacom back office and I haven't heard from him since, this was last week and Wednesday. Everytime I trust Vodacoms online process this happens.
