Rotten Meat sold at Supermarket

I am a regular supporter of our local Pick 'n Pay Supermarket but service with an attitude prevails!!! On numerous occasions at a further cost to me have I had to drive back to this supermarket to exchange meat that is rotten ... and in the process be treated with a bad attitude from the staff and management. Has anybody ever heard of mince being sold at any supermarket with a one day shelf life ... because this is a FIRM statement made by the butchery manager. I suggest any paying customers with hard earned cash purchase their meat from a reputable butcher instead of an outlet with mince that only has \a one day shelf life .... you will save yourself a lot of time
