Very bad application

### 1/5 — It is not working.

*2022-07-11*

It is all a lie. It never worked. And it says 3 days trial and when I canceled the subscription, it won’t cancel and did not refunded me the deducted fees for the yearly plan.

**Developer response:** Hello, we are very sorry that you give the application a low rating. Subscription must be canceled within three days, not after three days. We would appreciate it if you could write to us at support@whoiscalling.app. We will be pleased to help you solve your problem.
Best Regards, Team WIC

### 1/5 — من اول ماتفتح التطبيق يطلب منك الشراء وبسعر مرتفع
