Giant Eagle at Market District, Pittsburgh, PA Overcharged many times, and sell bad food Pittsburgh PA

This shop has two or three ways to overcharge..... The one, if I go to the electronic cashier (and it is almost impossible to find a humal cashier) is to mis-bill the item, so today I entered 'nectarines', the machine said 'nectarines' back to me..... but on the bill it listed them as 'peaches' which $1 per pound higher. The other ways are for them to advertize 'but 1 get a second free' but when I scan the second it is not free

I catch these, and go to the customer service to get my money back (on good days I just leave the electronic cashier, but again I have to start from the beginning on another cashier), but then I normally have to wait at least half an hour while either the cashier is not there or is dealing with other people (who've probably also been overcharged!).

The other thing is the crappy food - mainly fruit and vegetables. Many feel and/or taste as if they have been kept in the fridge (or sometimes they are so bad they feel as if they were kept in the freezer!) for 6 months.

They also have milk that tastes disgusting (their own-brand milk), they have chicken with injected water (they claim it has 'broth to add taste' but I'm quite sure what they really do is inject broth as it costs 5% as much to make as chicken does, do the customer must buy more to fill up.

I only stay with them because I do not have another shop to go to, as, in Pittsburgh, they have an almost complete monopoly of the city - and they badly abuse it
