Hotel.de has advised that your hotel has been deactivated from their website due to unpaid commissions. This means that you are no longer able to be booked through this channel and, in a number of cases, the outstanding commissions and then forwarded to that lawyers or debt collection agencies.
I am writing to you to bring this to your attention. I have only a summary of the amount outstanding but understand that the agency or the representatives have been contacting hotels directly with details. Please pay any commissions that are due and contact hotel.de directly if you have any questions
