Dundee United manager Craig Brewster is furious with his former club Inverness Caledonian Thistle's handling of his bids for David Proctor and Ian Black.
United lodged formal offers for the pair last week, but Caley's director of football, Graeme Bennett, is still to respond.
"I'm still waiting as far as Proctor is concerned," Brewster told the Daily Record.
"Their director of football was supposed to phone me back but it hasn't happened. I can't really remember them doing business like this in the past.
"They said they would not stand in Proctor's way so I don't see the reason for their delay.
"I also put in a bid for Ian Black over a week ago but there's still no answer on that either."
