Need to get order for Adobe Photoshop 13 amended to reflect 32 bit system and for second order for same system deleted.

I accidentally deleted partially completed order for for Adobe Photoshop 13.  It had my credit card info filled in but not the size of the computer (32 bit VS 64 bit)  I need order page to reflect 32 bit.  Trying to recover original order, I reordered a second Photoshop 13 by mistake and need it to be deleted . I don't know how to get corrections done?
