The given situation is possible because of two reasons:

1. It is impossible to display the counters of virtual4 and also some other operators correctly. In this case it is necessary to change the operator and country;.
2. There is an adaptive rating system on the website. If you click "Cancel" or "Ban"many times, your account can be blocked for 1 (one) hour;.

In order to check the rating status, try to buy a number through the web-panel and the website will show a message about the low rating.
