Boateng crushed Ballack’s hopes of playing for Germany in the World Cup with a horror tackle in the FA Cup Final earlier this month.
“Boateng has not been in touch,” said Ballack.
“He apologised in public because he got a lot of pressure from the press.
“It would be a normal reaction if you have put somebody out – whether on purpose or not. It should be normal, but he hasn’t been in touch.”
