I have got your point and point of them too. According to you, you have submitted the perfect document at 2nd time while for the first time you have provided wrong information. I do not think there had any problems for that. But I think you have created multi account knowingly or unknowingly.
How it's possible unknowingly: I have only 1 TRX wallet and no one else used my PC last month :/
It may happen for other wallet. I man you may use other wallet for example, dogecoin, ethereum, litecoin and so on. Also you are saying no one has used your pc for last month but it might be used longer ago then last months. They may trace for a long period of times.
