Fighting back against supermarkets

Asda have a new offer on 500g Readybrek packs, now available at "2 for £3" - don't buy it for a minute!

Shortly before [Read: In the last 7 days] this fantastic "offer" for customers was advertised on shelf and on their website, the actual price of readybrek was, yes you guessed it, £1.50 per pack.
At the same time as the "2 for £3" offer came on, asda increased the regular price of readybrek 500g packs from £1.50 to £2.18 (this is a staggering 45% price increase)

At a time when family budgets are stretched to breaking point, we could well do without mismarketing and deceptive practices from a supermarket, which advertises that they are "saving you money everyday" - the simple message to them, is stop playing corporate games with people's household budgets!

I did ask Asda (and the new twitter account "asdahelp" - which doesn't show up in #asda search results) how this readybrek "2 for £3" was an offer, they declined to answer, not once, but FOUR TIMES!
We did get a new follower - asda service team - but no response from them either. (How many twitter accounts do they need/staff?)
Asda's silence speaks volumes, I don't know how they get away with it!
