Soregies Not Debiting Bank Account

[pastelpainter]

Thank you Fred, for your kind reply.  
We've been customers since 2003 using prelevement without interruption until recently. I often get online to check out previous factures including the latest. I am now composing an email message to send through the facility provided on their site and we'll take it from there (hopefully they will read it and reply ;-)

Thanks again and wishing you a fine day...

Moi again Fred,

So, before sending off a heated missive to Soregies,  I've had a search through our bank statements of the last year or so and, as Brian as mentioned, yes there are inconsistencies in the billing which seem to have little logic. A couple of years ago we happily received a facture with nothing owed and another time they owed us! Doesn't happen enough for me! 
Anyhow, as to my current situation (and this may apply to others'), what seems to have evolved is a billing that debits 20-some days (maybe a little less or more) after the date of the facture itself (not the email date when you receive it.) This shows up on the following month's bank statement. For example, if the facture is in July then August's bank statement should show that debit. I therefore expect to see a debit on April's bank statement as our last facture was for this month, March. I hope this does help people who are confused by the Soregies billing system. And who knows? It may evolve into something else yet again. Yikes!
So, no need to send a letter so far. Hooray!

A note on analyzing the facture itself. There is an explanation on their site and I will test out my new Reverso Document Translator and, if you think it's the right thing to do, I will post the English translation on this forum. 

All best to you and Brian,
