If i may just add to this it would be prudent to cancel your credit card that you use for this account to be on the safe side
All passwords and email address should of course be changed in the meantime all passwords should of course be both upper and lower case wherever possible
Also if you have accounts with any business that you purchase from just make sure that you change the passwords on these accounts from time to time and also the credit /debit card not just let the account run in a dormant mode
If your not using it delete the account also try your best to use a different password for every account that you have irrespective of how complicated the password is
