Your best bet would be to contact Server4Sale directly as they resale for multiple datacenters. If I am not mistaken they give you access to Soft Layer's customer portal where you can reload your OS from there at no charge but not sure about their Burst.Net offerings.
You can post a review, etc.. but asking questions that should be directed to the company at hand is pretty worthless. Try contacting S4S and they will help you out.
