Nikolay Davydenko is unhappy with the way the governing body of men's tennis is handling the investigation into possible match fixing, says his lawyer.
Davydenko is in Shanghai for the season-ending Masters Cup
The Russian refuses to hand his phone records to an investigation of a match featuring irregular betting patterns.
"If you want somebody's co-operation you talk to him," said Frank Immengal.
"You don't just send him a request for something while he's playing the US Open. At that point you have to expect that he's not going to co-operate."
Immengal told BBC Radio 5 Live's Sportsweek: "An organisation like the ATP, which is responsible for its players, cannot go on like that."
Online betting exchange Betfair voided bets on a match in Poland in August between Davydenko and the 87th-ranked Argentine Martin Vassallo Arguello.
Davydenko retired injured in the third set, and it has since emerged that nine people based in Russia had bet US$1.5m on him losing.
Former Scotland Yard detectives working on the ATP investigation have this week interviewed Davydenko and members of his family, asking for all of his telephone records.
And despite directing his client to refuse, Immengal has revealed that Davydenko will have to hand over the records eventually.
"I know that my client is truly innocent so I already know that they will reveal nothing," he said.
"We have seen this before and it is only a formality. We both know they have to sign the ATP code for players and they have to hand out telephone records."
People ask me: true or not? It can bother you
More controversy followed for Davydenko at the St Petersburg Open on 26 October when he was fined $2,000 for not trying hard enough against Marin Cilic.
And at the Paris Masters on 1 November the world number four was told by umpire Cedric Mourier to "try your best" after the official questioned why he was serving so many double faults against Marcos Baghdatis.
Immengal said: "I would really like to have an explanation for that and I have already sent two letters to the ATP asking them to come out with a statement (on) what they think about what has happened.
"For me it's unbelievable - it's so unfair," he said, before adding: "I believe it's a coincidence, yes."
Speaking in Shanghai on Saturday ahead of the Masters Cup, Davydenko said: "I'm very angry.
"If you read something in the press, it's bad news. People ask me: true or not? It can bother you."
