Under weight packaging

I have been dissapointed by this company, who for close on 3 months I have been trying to show that their prepackaged 1 or 500g meats are not the weight they claim. That this has gone unnoticed I human error I hope, that they refuse to do anything about it, I hoped was a little embarrassment or perhaps "red tape" BUT after having to call Customer Care and leave messages to receive no response and when I did finally get to speak to someone, not only did this person challenge my statement that I had left messages (again I accepted as being embarrassed, esp. when she admitted she had received a message from me but had not responded), but gave me her word that the person heading the packaging would contact me.

I have waited a week and no one has called me, neither has the problem been resolved.

I called Head Office again yesterday and after three calls, left a message l, which has still not been returned.

Now I begin to wonder if this human error or creative accounting. Embarrassment or ignor till the person goes away?
