I had 2 delays with the same air company in the same trip. On the one-way (flight A), I asked for FlightHelp's support because it was the first time in my life. For the return (3 days later) (flight B), I did it on my own on the air company website.
Results:
Flight B --> I received 250 euros from the air company within 2 weeks from the request
Flight A --> FlightHelp disappeared for more than 1.5 month. After several requests of update, they asked me once again the same data I provided to open the claim. Finally, they sent me 115.30 euros (46% of the 250 euros the air company gives back for 5 hours of delay).
TIP: if you want to be reimbursed correctly and timely, do not ever use FlightHelp
