I have been trying to cancell my free 10 day trial via email. No conformation has been received as of 4-11-2010. I will try calling the company first thing on Monday 4-12-2010. I do not wish to continue in the Simplebrite monthly shipment program. I had a reaction to the whitening gel. My mouth broke out in blisters and felt like it was burning inside. I do not wish to continue in this program. Please send me instructions on how to ship back the product. Please do not send any more Simplebrite Whitening gel. Please do not bill my credit card for any more product. Thank you. read full review »
