gingeralenz: We had some shifty guy come during the day and was hassling my wife to sign offering better deals etc. He came back later in the evening after dark and tried the hard sell on me, wouldnt take no for an answer and had to shut the door in his face while he was still talking. He looked offended when i said not interested! Got to say advertising is really in your face these days.
We've had similar recently, although in our case I wouldn't call the guy shifty - he did very clearly identify himself and show a Mercury ID card. However, he was pretty aggresive in trying to make us change.
The suggested savings obviously sound appealing but I was pretty sure there would be little real world difference at the end of the day (in fact looking now, powerswitch.org.nz suggests that it would be more expensive in our scenario). Normally I like to do my research and then choose my provider based on some careful thought but this guy wanted us to change then and there. I got the spiel about how they have a huge market share in Auckland (I haven't actually checked if that is true), why wouldn't I want to change? I have no idea how that is even remotely relevant to me in Canterbury but ok. I think his line of 'it's up to you, but if you dont like saving money...' must net results because it was used about 3-4 times.
When he realised he wasn't going to get me on price alone, the tactics suddenly changed to their 'wonderful coupon type offers' around the area offering discounts at restaurants / hotels and the like. This just struck me as ridiculous and a clear attempt to bait me with generic & token discounts rather than actually providing market leading service.
Overall I was pretty unimpressed, rightly or wrongly we're sticking with our current provider.
