The customer service is abysmal. Mandy is great but Amy is awful, telling me the tests weren't faulty because "I didn't like the results". What an absolutely ridiculous and unscientific thing to say. I received 2 faulty tests and they denied they were faulty. There is no way they have a 100% no faulty tests. It's disappointing as the previous tests were fine but these two, completely faulty and the CEO even removed my post about it on their forum because I told her the tests were faulty. So basically, they censor anyone if they don't like what they say, even though what I said was correct. I asked them to send me 2 tests (which I would pay for including the postage) so I could show them my tests were faulty and they refused. Of course! They don't want proof their tests are so dodgy. But not only this, Amy the CEO gave me unasked for and inappropriate medical advice, when she doesn't know my medical history or situation and besides, she was wrong on everything she said and wouldn't acknowledge it. She's not a doctor and should not be giving medical advice to people she doesn't know. Don't buy their tests. They will not help you if something is wrong with them. They just deny responsibility. Greedy, dodgy and unethical is how I see this company.
