Horrible customer service

I really loved this app until I upgraded phones and have not been able to log back in due to wrong password. I have sent numerous reset password requests and the hyperlinks D’O not work. I have contacted the support services via email because there is no contact number. This has been going on for 3 months and I still cannot get help!!!

A follow up review to a previous review.
I wrote the previous review due to frustration. However, the problem was resolved by their support services. I highly recommend CircleBack to anyone wanting a simplified app in keeping up with your contacts.

A unique and partially useful Contacts app with one serious issue

Alone of all the Contacts apps this remarkable address book will update changes in contact info, such as telephone number, addresses, and job data, through sophisticated web searches. These data changes are periodically presented for user inspection and approval and updating.

PROBLEM ISSUES: UPDATING: If you are unsure of the update info and select that option, no changes will be made, but you also lose the new data and it does not appear to be retrievable. This new data should be stored in a buffer to allow you edit and change contact at will, and only permanently delete when you finalize contact.

NOTES: This is a real deal breaker - Less than hundred words are maintained from original Apple Contact Notes. CircleBack appears to truncate the full length of the Contact Notes. This is totally unacceptable and dooms this app to infrequent use, rather than being a primary go-to app. Until they fix this I’ll use it for updating contacts, but little else. Too bad!
