<prompt> Human: Hello,Today, my wifes credit cart was cancelled by no apparent reason. She called to find out what was going on and the reason was her husband sent a letter requesting to be removed from the joint account.1. My wifes credit card is not a joint account, I helped her to open it online.2. Of course, I never sent a letterHow is this even possible? is there some chance for this to happen? like someones wife having the same name as my wife and being this an error?Also, wanted to ask to anyone with a citi credit card joint account. How does the statement looks like? does it has both names? Customer support has been of little help, they did not provided the name of her husband or any further details except asking her to check with her husband I am a bit worried about some fraudulent activity being involved but we checked Kredit Karma and everything looks fine.  <response>: Have her escalate the issue to a managersupervisor and explain what happened. She could also go into a branch with 2 forms of ID and they should be able to help from there as well. Sounds like it may have been done in error. Keep calm when you approach them, goes a long way. Keep us updated!
