A high-profile cryptocurrency trader that uses film star Matt Damon in its advertising mistakenly transferred almost $10.5million to aMelbournewoman.

Crypto.com launched legal action against Thevamanogari Manivel and her sister Thilagavathy Gangadory after taking seven months to realise its mistake.

The error happened when the company attempted to give Ms Manivel a $100 refund in May 2021, but entered an account number in the payment section of the transfer.

The $10,474,143 mistake was discovered in a company audit just before lastChristmas.

When Crypto.com tried to get its money back, $1.35million had already been spent on a luxury five-bedroom house and the rest had been moved to other accounts.

The house in the Melbourne suburb ofCraigieburn, which hasfour bathrooms, a home gym and cinema, was bought on February 3, theHerald Sunreported.

On February 7, Crypto.com made freezing orders against Ms Manivel's bank account, but court documents show $10.1m had already been moved to a different joint account and $430,000 had been transferred to her daughter, Raveena Vijian.

The house registration was then transferred to the Malaysia-based Ms Gangadory before Crypto.com was able to take out freezing orders against her in March.

The company subsequently took legal action in the Supreme Court against Ms Gangadory seeking to get back the cost of the house plus 10 per cent interest.

The court heard that she was 'seeking legal ­advice' and her lawyers 'would be in contact', but neither she nor they appeared.

Judge James Dudley Elliottordered Ms Gangadory pay Crypto.com $1.35million, interest of $27,369 and costs, and that the Craigieburn house be sold.

The Victorian Supreme Court'scommercial division heard the case in May, with reasons for Justice Elliott'sjudgmentbeing made available last week.

Because Ms Gangadory was not represented in court, Justice Elliott wrote that 'references to the facts of this case based on such uncontested evidence are necessarily open to challenge if Gangadory ever seeks to set aside the default judgment'.

The judge added that she 'has not responded to any of the correspondence from (Crypto.com's) solicitors' and that 'the effect of not filing an appearance is that the allegations in the statement of claim are taken to be admitted'.

Seperate orders have reportedly been made regarding the rest of the money mistakenly transferred to Ms Manivel.

Crypto.com's lawyers, Cornwalls Law, told Daily Mail Australia that as the matter is before the courts, it was unable to comment.

Ms Manivel and Ms Gangadory could not be contacted.
