Pie gone bad

On Tuesday (19th May 2015) I purchased a Piemans pie from the total garage opp gateway only to find out (after a bite) that the pie was gone bad...the mutton curry was actually slimy and had a foul smell...<br> <br> when I returned the Pie, the manager informed me that they just bake the pies and cant answer why it is bad and Pieman's are the ones who can provide an answers after the pie visits the laboratory<br> <br> Can you please look into?
