ipad & iphone have been compromised
Someone has supposedly used a clean up app on my iPhone &amp; iPad.


That would be you. Where did you install the app from? Is your phone jailbroken with strange apps installed from random websites? 


  My name was in my contact list. Clicked on it &amp; found my email accounts &amp; Twitter.


That's normal. you are supposed to have a record in Contacts that identifies you.

It is highly unlikely that your phone has been compromised. You may remember recently that the FBI had some difficulty getting into one. Malware is basically non-existant on the iPhone platform.

However, it is quite likely that your iCloud account has been compromised if you used poor passwords ("Karen1234", "P@ssw0rd" and so on.)


  He has been linking all my accounts, apps, etc.


Who is "He"? A google technician won't do that. Someone pretending to be a google technician might try in order to get access to your account. 

Big question: have you told your account password to anyone for any reason? If yes, change it now. And don't do that again.
