tide pen stained my shirt

I recently just purchased two 3 packs of tide to go pens and I used it on my white shirt and also my sons white shirt and it made both of our shirts turn yellow where the tide pen was applied. im so dissapointed because I could of removed the stains with something else and instead i used your product and it ruined both shirts.
