Who do Vodafone think they are?

Look at this ad from Vodafone. I think it is a smear campaign against Telecom's XT network, especially one part (which is too small to read on this photo) where Vodafone calls itself "New Zealand's reliable mobile network". That part can be taken to mean that other mobile networks in New Zealand like Telecom and 2degrees aren't reliable.

The phone being offered looks nice but there is no way that I'm recommending that anyone on Telecom defect to Vodafone if Vodafone have that sort of attitude. I just hope those losers at Vodafone can afford a good lawyer in case they end up in court over this.
