I mention this, only to warn other, potential complainants, of the ways they're likely to be fobbed off - and to note that at least Vodafone are admitting that the network is "variable"...

I have checked your account and can confirm that the 2G and the 3G network in your area is variable. I request you to purchase the sure signal from the nearest Vodafone store to enhance the signal strength in your house.
As Peter Bell has suggested, we need as many people as possible to contact Vodafone.
