I applied for the Credit One card 2 weeks ago and was approved. I received my card today and when I went to activate it they said I needed to send in my birth certificate. I asked why if I was already approved and had the card. They said because someone else had applied for the card and used my address or somethinc like that. I just went ahead and told them that I was not submitting it and to go ahead cancel everything. Since the card was not activated, will it hurt me?
