Our client is looking for a complaint management solution for their guests. For example, a passenger left a bag on the bus. Customers contact you via email, but it's not properly documented. They are obligated to do so. The software solution should be able to: For example, a customer scans a QR code, which redirects them directly to the complaint management system. There, they describe their concern, and the information is then forwarded to the responsible department. This should allow them to see the current status of the complaint. It must be possible to assign tasks to colleagues. The progress of the complaint should be visible from the beginning until it is resolved. The customer would be willing to pay up to €300 per month or purchase this solution once. The amount was not disclosed.
