Had a rancid eucalyptus oil from this company. Told customer service who palmed me off saying 'all natural products smell differently which is a load of rubbish. I have had many eucalyptus oils, organic and non organic from a variety of other companies and never had an issue or a vile smell like this. Each product comes with a batch number but they had no interest in the batch number, or asking me to send it back as proof. They told me they advise their customers to buy a small bottle to ensure they are happy with it first. Cant even believe it. Personally I will never use the company again and I would advise you to do the same. There are so many brilliant retailers out there for essential oils why use a company that provides this level of service.
