Oussama Services is the residents’ app of Oussama Promotion Immobilière. Here is how to get help.
In immediate danger — fire, gas, someone injured — call the Civil Protection on 14 first.
Can’t sign in?
The app recognises you by the number your residence recorded, and sends you a code by SMS or WhatsApp. If the code does not arrive, or your number has changed, your residence’s concierge can check it.
No account yet?
Accounts are created by your residence, for its owners, its tenants and their households. Speak to its concierge.
Frequently asked questions
How do I report a problem?
Tap Report in the bottom bar, or a category on the home screen. Describe what is happening, add a photo if it helps, then tap “Send to customer service”. The request is created when you send it, and you follow it in Requests.
What is urgency for?
Normal, High or Urgent: it helps customer service deal with what is pressing first. The app suggests one based on the category, and you can change it before sending. In immediate danger, call the Civil Protection on 14 first.
Can I add photos?
Yes, with the Photo button while writing the request, or with the camera in the conversation. Each file can be up to 25 MB.
What if I have no network?
Messages written in a conversation wait on the phone and go out by themselves, once, when the network is back. Conversations you have already opened stay readable.
When am I notified?
When customer service replies, when work starts, when a request is resolved and when your residence publishes an announcement. You can turn notifications off from your profile.
How do I reach the concierge?
The Directory tab shows its hours and number, along with your residence’s other numbers and the emergency numbers. From a request’s tracking screen, the phone button calls it too.
