Hello, apologies for writing in English. I jsut discovered that I have been wrongly invoiced sms costs under Bizz XL20 for over 6 months. I could claim reimboursement for the last three months but for the previous months I need to do it in writing. !!

I cannot find to whom I should write. Can you please give me an address email?

I would also like to ask: if this is a technical problem as the operator said, and Proximus knows about it... why does not Proximus contact the clients about the problem or simply create automatic credit notes to reimbourse the money wrongly invoiced? That would bring some trust to clients.

thanks in advance
