Coloblast is an unscrupulous company based in Puerto Rico that claims to offer "free" trials of their weight loss, colon cleasing vitamin. They send it to you then tell you the details AFTER billing your credit card for over $100 in charges. They Claim to offer a refund but the unsaid "small print" is based on a long term contract. I was told to cancel my subscription to get a refund, then later told that DUE TO the cancellation I was not authorized to get a refund. Utter scam. Even my credit card company is familiar with this FRAUDULENT international scam. DO NOT PURCHASE Anything at Anytime from these bottom feeders! read full review »
