It is very important for us to verify that humans are using our tools and that computer programs also known as bots can't. It is very hard for computer programs to complete our offers and pass our lockers and therefore automate the whole process. We hope you understand why we must lock the one-time verification codes with short offers and the risks of not doing so.
Javacript must be enabled in order to get the verification code.
If the verification code you got didn't work for you, then someone most probably used that verification code by brute forcing the verification code using bots. In that case you should just refresh the page and get another verification code.
