Dont make a promise you cant keep

<p>Bought a marked off item on Tuesday. Came to the till and suprise suprise it scans the wrong amount. I make the cashier aware of this and I am told to go and fetch the price tag. Off I go and bring it back supervisor is called and look at it. I remind them of the double the difference promise but is quickly told only if the discount price has a barcode on. Guess thats the PNP fineprint then. Asked to get it at marked down price and is told have to ask manager first and I wait. After a while told cashier just complete transaction I have to leave. On my way out person comes back they can give it at marked down price.. Really... reported to PnP consumer line and is told I will be called. 2 days and still waiting. Guess they not calling. Really hate to shop at PnP not sure why I do this to myself </p>
