Bad attitude from call centre agent and disrespect, ***** deals with vodacom, saying goods will be received tuesay, monday say don't have stock and after say I cancelled, which I have not approve for cancellation

Made a online purchase for haewai P10 lite and P9 lite, call centre called Me Friday 01-12-2017, everything was approved and agent said I will receive on tuesday which will be delivered, today is Monday I called In to say where I will be so they can delivered, the lady that answered 1st said they don't have stock and said again that I cancelled when I did not, they cut my call and I called repeatedly they acted like they could not ear me, I have recordings of them which I will take further action.
