Support, billing, privacy requests and security reports all go to the same place. There is no queue to pick and no wrong department to land in.
Written in English or Arabic, whichever you prefer. It is read by a person, not a ticket queue, so a reply may take a day or two rather than minutes.
Tell us what you uploaded and what you expected. A run link helps more than a screenshot, because it lets us look at the same rows you are looking at.
Changing plan, a payment that did not go through, an invoice you need for your records, or a month that ran long.
Access, correction, export or deletion of personal data, including on behalf of someone whose statements you uploaded. The Privacy Policy sets out what we hold and for how long.
Report it here before anywhere else and give us a reasonable chance to fix it. We will not pursue anyone acting in good faith, and we will credit you if you want to be credited.
The Terms of Service, Privacy Policy and Cookie Policy all point here too.
