Good question. If the jewelry store opened up several credit card accounts for you without your permission but no unauthorized charges were made on the accounts, you can file a lawsuit about the situation, but you have no damages to complain about in terms of dollars and cents to be rewarded for as a matter of law.As such, it would make no economic sense to file a lawsuit over the situation you are writing about. However, speaking with the jewelry store's manager or owner would seem proper to voice your displeasure over what happened.
