Expired bread

Last month I purchased a loaf of rye bread at Spar in Blackheath nd it had green and white mould before the expiring date I returned it nd they seemed unapologetic about it nd said I should take something else. I bought another loaf a day ago nd the same thing is happening. The bread expires on the 24th but yet it has mould today on the 22nd. It is from a bakery called Black Forest Bakery Tel: ********** but it's distributed by spar Tel: **********
