Need accounts merged.

I have multiple launchpad accounts I would like merged, but most have registered email addresses I no longer have access to. Please merge the accounts with the following addresses:

<email address hidden>
<email address hidden>
<email address hidden>

I tried changing the email address associated with the oldest account (<email address hidden>) to my current email address (<email address hidden>). I carried out the confirmation procedure and changed the address under account details, but launchpad will not let me login with this gmail address, once the accounts are merged, please send me an email with instructions on how to log in and reset my password. Thanks!
