can someone please tell me exactly what process i should follow to cancel this. i had the above two name take various amounts from my account. i foolishly had the 'free' trial for dazzlesmaile / ultra white. are the above names the same company?

Should i make contact with my credit card company first explain the issue and then contact this company - is the number 0-808-120-1987 by the way? ive read on other forums that i will get a cancellation number what am i supposed to do with the number? would appreciate help from anyone who has gone through this and can help this poor unfortunate soul!

many, many thanks!
