Google script Execution failed: please try again later and consider using batch operations. The user is over quota - google-apps-script

Question

I have a script where I'm syncing my google contacts with google spreadsheet.
I have around 11000 contacts in my account and I've written a function getContacts which fetches all contact information from the google contacts and sends it to a function printContacts,how ever as there are too many contacts the script fails to execute to completion.
I tried using the code to create a trigger everytime the max execution time is reached but now I'm facing a new problem,as I have too many ContactsApi call the script is showing an error saying 'user quota exceeded'
If anyone can get this code to work,it'd be a great help
