The reason is, Deleting a contact require POST request, but a GET request in being sent.

To Reproduce
Steps to reproduce the behavior:

1. Go to any customer profile
2. Click on 'Add Contact'
3. Provide contact name and click 'Save'
4. Now click 'Edit' on the contact you just added
5. Finally click 'Delete' to delete the contact

Expected behavior
The expected behavior is the customer contact gets deleted

Screenshots

Additional context
The issue is in the file:-

iris-web/source/app/static/assets/js/iris/view.customers.js

Line 36 in 0f702c0

get_request_api('/manage/customers/' + customer_id + '/contacts/' + contact_id + '/delete')

The code is sending a GET request, and this has been deprecated.
It should be changed to the following:-

            post_request_api('/manage/customers/' + customer_id + '/contacts/' + contact_id + '/delete')
