Commercial conditions for affected clients

My VPS was located in SBG1 and I have been informed that it can not be put back into service.
Therefore, I am assuming that the solution is to order a new VPS and I will get some kind of refund.
But the problem is that the VPS I had (VPS Cloud RAM 1) is no longer available for new contracts, the VPS available do not have the same technical specifications I had, and the prices are significantly higher.
It seems obvious to me that all clients affected should have the right to choose the exact same commercial and technical conditions they had before the accident, especially because we have been waiting a long time for a solution and we are loosing clients every day because of this.
I ask you to please tell me how can I contact the commercial department in order to solve this?
