And they say they are the best network

I just had the worst days, as I was looking forward to having my new phone today, as Vodacom's error become my problem they advertised the phone for R349 in their October catalogue, when me and my friend app**** for the phones, he had to get his yesterday and me today, to my surprise this morning at work he didn't have the phone, when asked he told me that when he went to complete the process and collect his phone, the sales agent told him that they made a mistake in the catalogue and the price is R 499 for the phone, he said he would think about it, this morning when I called the agent that was helping me told me the same thing, we than decided to call head office in hope that they can assist, when we spoke to a agent at head office he told us about the T&C's and the other one referred as back to the shop's saying that they must give us the phone at the advertised price of R349, they did not recall their catalogue but still has it at shops and is unwilling to assist they should be assisting us in this regard by telling the agents what to, but left us to fend for ourselves, this just made me lose faith in the company and their customer relations department,
