Expired produce.

I did my shopping there yesterday. Bought some polony and realized this morning it is now 3 days oast the sell by date. It smells sour. Spoke to the store and their option is to freeze it and bring it back at my convenience which means I have to remember and drive there. They sold me expired goods surely they should have the cost and inconvenience of sorting this issue. They'd be welcome to collect from my house. I also have the product and till slip.
