New package sticker date on rotten chicken hearts pack.

20 march 2024,i bought chicken, it was rotten and and smelling horribly, the package date was pasted on today's date, and the sticker look clean. They are repasting the sell by sticker on old meat. This was the worse experience.when I go back to speak to the manager he told me to get my refund and leave the shop, no apologies or any remorse.
