i told i'll update you guyz
support was so helpful and replaced my proxies
their answer:
I'm sorry for big delay. Our technical administrator was not online during weekend.
We got some problems on one of our servers.
We discovered that one of our customer burnt a lot of proxies and we make essential actions to protect rest of our customers.
We decided to replace your proxies to other server. You don't see changes, because we replaced your OUTPUT (back-end) proxies (INPUT [front-end] proxies are the same).
Try to use that one time more. If you don't be satisfied, we will refund your money with no problems!
Thank you for understanding. If you be satisfied, we will add you 2 days more like compensation.
If you got some questions, don't hesitate to ask them.
I'm sorry for inconveniences.
With all due respect
