20+ years "Valued Vodacom Customer" - really???

I have been trying to get a delivery from Vodacom for an upgrade ordered online on the 15th Feb. First they had the wrong address, then they didn't inform the Courier company of the new address. Then I had to change the address again (Monday 25th Feb), because I had returned to work after the break. I was phoned on Monday, saying they had processed my request and would email the new address to RAM at that moment, and to date RAM has nothing. I have spent HOURS on the phone; the latest I was told is that there is no record of my call on Monday to them, or their call to me. Since last week Thursday I have spent HOURS on the phone to VODACOM trying to sort this out. I am FED UP!!!
