A Little Shady???

After being a member for about 7 years, I changed my account to add my husband. He had apparently had an account there two years previous to opening the joint account. He owed money, and when we opened the joint account, no one made mention of this. But two years later they just took the money from our joint account. No notice, no phone call...nothing to tell us that they were taking the money. We are on a limited budget and the money withdrawn put us in the hole. When I contacted the bank, they said there was nothing they could do but they would reprimand the person who opened the joint account for not mentioning the money owed. That did us NO good. This situation was infortunate considering up until that point they had been a good credit union. Now I don't trust them...the account is still open...but NO money goes into it.
