Delete Bank Accounts - Start from Scratch

Delete Bank Accounts - Start from Scratch

We have had a Zoho Representative wipe out our entire account so we could start completely over.  But somehow the old contacts and old bank transactions have shown up in the new account before we even started to customize anything.  

I looked in the forum to see if there was any info on how to delete accounts or transactions - and tried to use the suggestions but they don't seem to be relevant because when I go to the accountant tab as it says, 'hovering over accounts' doesn't give me an option to 'show transactions' and when I try to delete transactions it says it will not be deleted, only hidden.  When I hover over an account it does show some icons off to the right, and one of them is a 'delete icon' but when I click on it, nothing happens.
