Poor customer service

I went to Sammy Marks to do an exchange of the same value on a Supersport Golfer and i didn't have a receipt.I was told by Petunia a Manager and Inno cashier I need to have a slip or I should know where and which date I bought it in order for them to call the store I bought from \for audit purpose"I know where I bought it from but unfortunately i don't remember the date.I was told there's nothing they can do end of story.Your policy reads as follows:Should you not have a till slip "
