dishonesty rife with chain stores

I am so frustrated by the blatant dishonesty and ***** been committed by our major supermarket chains (Pick n Pay, Checkers and Spar) wherein in most instances these days I have to get into a argument at the teller because prices been rung up (mainly specials) are never the advertised price. If you are unaware of this you get ****** blatantly. Disappointing in our country where the oversight authorities do not perform their functions across the board resulting in this malpractise taking place unaccounted for. This is what happens when you live in a banana republic with *******ion the order of the day.... makes me think about the ***** that pick pockets you when listed companies do the same ...just more sophisticated. Amazingly, I have not yet experience a item been under priced..."mistakes" are always in the retailers favour.
