“My Contacts Are Deleting On My Phone, Help”

Hello guys,

Two days ago, i noticed some contacts are missing on my phone because I found out they are no longer saved, i only see the numbers on my WhatsApp chat list. This morning, it got worst. So i went to check my contact list and discovered that my contact that was over 300 is now 124 shocked

. Please tech gurus, what could have caused that, and how can i get my contacts back? Some very important contacts to my life are missing.

NB: I saved my contacts in my google account
