Business ProfileforTelComm Credit Union

I have been attempting to sever ties with this Financial Institution for some time. Today, 9/19/23 I contacted them to attempt to have my name removed from join account# 402711000 as the other named individual and I are divorced. I asked they email me the instructions as I no longer reside in the state of Missouri where they are located. When the read off the email address on record it was wrong. I informed them it had been updated online. Their reply was your online account information does not reflect what they keep on your internal records. This would be the first financial institution I have ever dealt with that does this... I was told in order to change the email I would need to sign a form. The form would have to be mailed to the address on record, again in Missouri. At one point, I believe during the email address issue I was hung up on for no reason. When I called back, obviously upset I stated several times I want to do everything in my power to NOT do business, nor be associated with Telcomm Credit Union any longer. The employee I was dealing with got an obvious attitude, and the conversation devolved from there becoming a yelling match and non-productive. This is not the first time I have had employees at Telcomm Credit Union be condescending, or rude. I have had enough with this organization and I want my name removed from the joint account. As they only have 3 options when calling, and the department I need to deal with has an obvious bias towards me this is preventing me from doing what needs to be done.
