Did you check your Transaction History pages to see all details ?
If decution(s) from previous reservation(s), it should be listed.
Also if resolution centre was involved
If it is a long term reservation, the 1th installment is paid out ?
Just some suggestions you maybe can check yourself.
Hope this helps,
