I'm unable to contact the number for customer service 1 866 300 4437. Continuous busy signal every call I make. Some thing is not right with this company. I can't take the product, Doctors advice. So I need to return the order before 30 days is up. Please help me. I've read other complaints and it's the same as mine, unable to make contact with them. The enclosed a rebate email address and it's a bank here it is RebateProcessingCenter.net it's nothing to do with a rebate. Not right, red flags!
