Non-existient customer support. The actual service is great mostly. However, if you have any problems, which you likely will eventually, there is zero customer support. The only help they seem to offer is an online Faq page. No phone number, no email, just an in-app automated chat which will always end up directing you to the faq page, even if you specifically tell them you problem isn't solved there.

Recover WhatsApp backup from icloud I tried to get help and support from WhatsApp to recover my WhatsApp chat from iCloud but they just don't bother to help! If WhatsApp has feature to backup chat into iCloud protected by password then it must allow to recover forgotten password!! WhatsApp support centre is a complete failure to help and they don't talk over the phone just email a link go through it , and its all useless! Even they asked some screenshots of the issue but still nothing they have done! I am at last attempt and if entered a wrong password then the data will be lost!! so disappointing and unprofessional services from WhatsApp

My account got hacked however I had to… My account got hacked however I had to wait 12 hours for a new verification code. When the 12 hours were up was messaged to wait another 12 hours. Watsapp Support ignorant of this. Keep stating to reinstall app etc

No technical support, terrible support via email. In fact no support anywhere!! I had to delete the App and reload to save memory on my phone. Which I’ve done before, then logged back in. This time I can’t get back in. Customer support via email is terrible as I just get automated messages with which I get nowhere and there is no proper way to get real support when a problem does arise. I really liked using WhatsApp, but now I can’t even get into it!!

Missing Credibility If you don’t care of your data, your chat archive, and all your memories suddenly, without warning. All you have to do is use the WhatsApp program...they canceled and deleted my account and the accounts of dozens of friends without reason or notice. This program also clearly stands on the side of the Zionists who kill women and children and does not respond to objection messages. This is the same policy followed in the occupied territories.
