Hi and welcome

A few little tips from what I read in your post.

WE WAITED A WEEK AND THEN WENT TO GET OUR PERFECT SNAKE...DOCILE BUT ACTIVE...WORKER SAID FEEDING GOOD ON FROZEN FUZZIES AND FED WEEKLY ON SUNDAYS. (I THINK THEY LIE ABOUT THIS, AS THEY DONT HAVE ANY INFO ON THE INDIVIDUAL SNAKES). SHE SAID WE WOULD HAVE TO TAKE IT TO AN EXOTIC VET TO FIND OUT SEX. WE BOUGHT A REPTILE KIT(ALL INCLUSIVE), 3 FUZZIES, SOME CLIMBING BRANCHES AND A VINE. WE HAVE HAD HE OR SHE 2 WEEKS. ALL OF US LOVE DIAMOND. (MY SON NAMED). STILL WILL NOT FEED, BUT WE ARE BEING VERY PATIENT. ALL-IN-ALL I THINK THIS WILL NOT BE OUR LAST BP.
First thing to remember is that BP are not active so if your BP is active during the day there is probably an issue. (under feeding, stress etc)

As far as feeding goes well knowing Pet store chains I seriously doubt your snake was eating on it's own due to their policy they feed F/T and often have to assist the snakes because of this (might not be the case but I would not doubt), I would highly recommend to switch to live (at least 3 to 4 feedings) to make sure your BP eats on it's own for you.

Once well established it will also be easier to switch your snake.

Also the prey size that was recommended is way too small for a BP, most hatchlings are started on Hoppers and quickly move to adult mice.

The rule is to feed something about the size of the girth of your snake (widest part of your BP's body)

If your BP is young he should be voracious and if food refusal persist I would strongly consider looking into husbandry. (snake kits sold in pet store often do not fit the needs of a specific species like BP)
