How can I recover a deleted purchased song from itunes?

I purchased a song on itunes 6/29/16 and accidentally deleted it from my itunes a few days later. I see it in my purchase history bill when I look through my account information but it is not in my recently purchased items. When I go into the itunes store it only gives me the option to buy it again, I was also unsuccessful in finding an itunes support number to call. Any help would be much appreciated, I also can't believe itunes doesn't have a support or customer service number to contact--does anyone one know of one? Thank you.
