I have had money paid into my bank account but wasnt entitled to it help?

Don't panic! This happened to me after my husband had a stroke and could no longer work for a major supermarket chain.......several times over the next few months his 'salary' appeared in the bank-even though he had finished with them.......I used the funds (he no longer was able to do any banking)......about 6 months later we got a letter from their bank--mistake--please replace the money! I called them -explained that my husband was no longer able to work, there was NO WAY it could be replaced, and they had to take some responsibility for their mistake....and the told me not to worry about it anymore, they would write it off. At worst you could offer to pay it off at �1 a week....no one can send you to jail if you offer to pay back.
