Former Scuderia Torro Rosso driver Sebastien Bourdais has accused his former employers of sacking him by text message.
The 30-year-old Frenchman was fired last month, and replaced for the Hungarian Grand Prix by Spanish teenager Jaime Alguersuari.
"The way they got rid of me was very disappointing," Bourdais, who recently reached an out-of-court settlement with the Red Bull-owned Toro Rosso team, told the French magazine Autohebdo.
"[Red Bull owner]Dietrich Mateschitz was at the Nurburgring but he did not speak with me. He did not call me. Everything was done by SMS, which to me has no style."
Four-time Champ Car title winner Bourdais did admit some blame for his failure to shine in F1, however.
Admitting it was the drivers' responsibility to adapt to a car, rather than have a car designed to his needs, he said: "That was never my best strength."
