You can't complain, because people just ask you to use it, they don't force you. You should say that you have to leave and don't need to continue detoxification. If he stays, you have to report it. If you have spent money, go and wash it. Pay attention next time, sometimes you will be shameless. If she had asked you to apply for a card, there was nothing she could do if you didn't. Besides, she said that the test would be free first, not to mention embarrassing. Just wash it next time. What else do you need to deal with? If she asks you to do it again, just say you don't want to do it for the time being or the money is limited. If they say it will take a few more times to see the effect, and you say no, you just want to try. I don't hold out much hope. If she wants to return it, just ignore it. There is no need to introduce so many good products.
I hope it helps you.
