Ghastly new "muesli" rusks at Pick 'n Pay

Pick 'n Pay has changed their muesli rusk recipe and are now selling a ghastly, sickly sweet rusk that tastes like syrup and sawdust. The letter below should be self explanatory.

"As can be seen, the sugar has almost been doubled, doubtless at the cost of "expensive" raisins, fat is up, and "saturates" and salt, which aren't half as bad as touted, have been reduced. These "Muesli Rusks" have for years been the only remaining edible rusks sold at PnP. Now, cleverly timed to coincide with the arrival of a new, pallid box, they have been transformed to sickly-sweet bricks of bran and bleached wheat muck, with almost nothing that remotely distinguishes them as being "muesli" rusks.

To be honest, I have not expected any better from an entity whose only aim is making money, no matter at what cost to their customers.

I shall return the boxes of rusks that I have bought and report this base and ********* action as widely as I can.

Regards"

I received a canned response that shows they haven't even bothered to read my complaint.
