Stepanova and her husband, Vitaly Stepanov, claim the IOC have offered them "no support" and have sought to use the situation only to benefit their "own position".

The Russians also that claim Bach and the IOC have deviated from their "zero tolerance" approach on doping. 

Speaking from a secretive location via conference call, Stepanova, a former 800 metres runner, and her husband, an ex-employee of the Russian Anti-Doping Agency, dismissed Bach's claims that the IOC had done more to help them that any other body.

The couple revealed they have not heard anything from Bach since a short letter on July 29.

"Thomas Bach doesn’t know anything about our situation," said Stepanova.

"He never made an attempt to sort things out and understand anything.

"They simply say what is going to serve them. 

"Yes, I admit I was part of that [Russian doping] system. 

"However, I decided I know longer want to be part of this and I told the truth. 

"Once again, the IOC or Thomas Bach do not try to understand our situation clearly - they simply take a position that’s going to be of their greatest benefit."

The pair had first approached the World Anti-Doping Agency (WADA) about allegations of state-sponsored doping in Russia.

But when they did not receive what they believed to be a satisfactory response they instead worked with German television channel ARD on a documentary.

After it was broadcast in December 2014 the International Association of Athletics Federations (IAAF) launched an investigation, which led to Russia being banned in November 2015.

Attempts to have the suspension lifted in time to compete here at the Olympic Games were unsuccessful. 

The IAAF, however, recommended that Stepanova - who had previously served a two-year doping ban - be allowed to compete at Rio 2016 in the hope it would encourage more athletes to become whistleblowers. 

The IOC, though, barred her from taking part.

This was, they claimed, due to her "long implication in a doping system" and that she "does not satisfy the ethical requirements for an athlete to enter the Olympic Games".

The couple were instead invited here to watch the Games, something they have dismissed as an "attempted bribe".

The IOC decision not to let Stepanova compete at Rio 2016 clashed with the views of the IAAF, WADA and much of the wider sports world.

Many claimed that the IOC had prioritised appeasing Russia over taking a firm stance.

IOC members Adam Pengilly, Richard Peterkin and Yang Yang all questioned the decision during the IOC Session here, with Pengilly claiming it has "harmed the fight against doping".

Stepanova and her husband are angry at Bach and doubts whether he should be leading the IOC. 

"I do not know if such behavior is ethical," Stepanov said. 

"But these people [Bach and other sports officials] should admit their mistakes and apologise. 

"I do not know how ethically suitable Thomas Bach is, I only hope that he admits they have made mistakes."

The couple have been forced to move locations after both Stepanova's email address and her Anti-Doping Administration & Management System (ADAMS) online whereabouts account were hacked.

They concluded somebody was trying to find their location.

Both are considered traitors in Russia who allegedly have made slanderous allegations against the country.

"We are taking every measure possible [to protect ourselves]," Stepanova said.

"At the same time, we know that if somebody really wanted to do something to us, they would probably succeed.

"What I would like to say that if something happens to us, all of you should know it would not be an accident.

"We are very worried about our safety because we have a small child."
