<prompt> Human: Background: I am active-duty military, I have an 800 credit score, I have never missed a credit card payment in any of my prior loan or current loans or any of my for existing credit card.Basically, I applied for the card on October 29, 2017, and was approved by Chase to get the card. I received the card on October 31, 2017 and then activated itused it that night to buy dinner. The next day on November 1, 2017 Chase abruptly canceled my reserve card with no reasonable explanation.Called Chase and subsequently worked my way up there chain of command, each individual not knowing exactly why it was canceled, but it was canceled in a general term of their banking policy. They are telling me that there is no other way to find out what is happening, other than to wait for a mailed letter from them in 2017. After finding all of this out, I immediately ran to check my credit and to get reports about if any shady activity was going on. Nope. Everything is fine and there is no reason why I should have been canceled. What sucks, is that they hard pulled my credit and that is going to stay on there for two years and I have nothing to show for it. They stated that I can re-apply for the card, but then again it would pull my credit again and Id have another hard pull. Bottom line: Chase fucking sucks and beware.  <response>: Cool I guess? I have 4 Chase cards over the past 5 years and have not had a single issue with them. Wait for the official mail correspondence yes, that still is the primary correspondence method for basically every bank in 2017 for major items and go from there.
