    Omigoshtaba - you need to attend basic elementary English classes and not ask this question here. – Blessed Geek Oct 27 '13 at 5:18

    "Did you contact them?" is the correct answer because it is grammatical. Blessed Geek has given you good advice, ELU is not a site designed to help beginners of English. – Mari-Lou A Oct 27 '13 at 7:35

    More to the point, this is a duplicate of a duplicate of a duplicate of a duplicate. (I am not exaggerating. This question gets asked once a week, every week.) And there's no point in migrating it to ELL, either, as it will be a duplicate of a duplicate there as well. So the real issue here is not whether you picked the most appropriate site, but whether you searched it before asking. Please make sure to always do just that. Thank you. – RegDwigнt Oct 27 '13 at 12:37

The auxiliary verb do, in all its parts (did, does, don't, didn't, doesn't) is always followed by the infinitive ("eat", "be", "contact") never by the past ("ate", "was", "contacted") or the past participle ("eaten", "been", "contacted").

  • Actually, of course, it is rarely followed by any form of be, but the point still stands. – Colin Fine Oct 28 '13 at 14:44
