Poor customer service no feedback

On the 22nd June I app**** online for a double deal recieved on the 27th June one phone I called soon as I received the order to cancel the upgrade the phone was picked up by ram courier on the 29th I was then told to wait 72 hours call again and request a reversal I've been calling every 3 days to cancel the upgrade of a phone I don't have it's going into 2 months now only for them to tell me the phone has not reached the warehouse and cannot be tracked I was debited for a phone I do not have and then asked to get a affidavit to say that the phone was picked up now they tell me email it to someone else and wait for investigation and feed back how can i pay for a phone that was collected and didn't reach the warehouse which is not my fault vodacom has been so unhelpful it took 1 month for them to realise that the phone did not reach the warehouse even though I've been calling every 3 days i spoke to over 20 consultants nobody noticed that something was of now I have to be paying for something that hasn't been used and wait for a reversal that's should of been done already every person tells me something different when I call its really frustrating not helpful at all I will not be taking any contracts with vodacom again
