Grants 360 /offerincome.com/kit after i cancled their service less then 24 hrs, they went and took 58.07 out of my account the day after i cancled Internet

on 6/16/09,8:53a.m. i went on line to hopefully find different grants for a small business loan and came up upon grants360, their first fee was $1.95, that was fine. but the more i got to thinking about it, i decided it wasn't right. so i e-mailed them to cancel at 6/18/09 at 4:19.a.m. according to my bank statement, they took the $58.07 out of my account on 6/19/09. i called my bank and cancelled that card, so i do have a new one. i have e-mailed them for a refund, they have offered me $40.00 back, but i am unwilling to give them my new card number, so i am going through my bank to dispute this. so far i don't have any answers yet. but how can they attack my account when i cancelled well before that? this is just a total rip-off!! please help!! thank you.
