We currently offer one free proxy replacement, per proxy, per 30 days. So if one of your proxies is not working to a site you using the proxies on, then you may use one of your replacements.
If you have used all your replacements, then you will receive more 30 days from the day that you used the replacements. So if you used the replacements 15 days into your 30 day billing period, then you will receive the new replacements 15 days into your next 30 day billing period.
If you would not like to wait for this, you are able to purchase additional replacements. Currently, you will need to speak with our support team and they will be able to assist you in completing this process at the link HERE.
We will be implementing a client friendly way of doing this soon.
To purchase additional replacements and for any other questions, contact our support team here: http://support.blazingseollc.com/support/tickets/new
