How Do I Cancel My Online Walmart Account?

I went online and made an online walmart account for buying items from the website. when i made the wishlist for later i was to create a primary recipient (me) and i DIDNT create a co-recipient. So when I try to add things to it i couldnt sign into my account because it requires a pin It was all changed my name was a capitalized and slightly spelled wrong and the co-reciepient was a ruben reyes ive never heard of this person i need to cancel it cause my name adress and phone number was required for the wishlist i want to cancel it before this reyes person messes with it even more !!!
