Sorry for my late response. Thank you for all of your patience while waiting for a reply. I just wanted to make sure that your issue is addressed. I can definitely understand how frustrating your situation must be. I would love to help you find a solution to this issue. I am afraid that there is no such option to increase the ring volume, or the ring/alert type sound. I apologize for this inconvenience, and thank you for your feedback if you have any.
Please let me know if you need further assistance.
