Joanna purchased a laptop from a Singaporean online company for $800. She signed an online contract with the company. Among others, the contract included the following terms and conditions:

2. The contract shall be governed by Singaporean law.

6. The Australian Consumer Law does not apply to this contract.

15. The parties explicitly agree that ACL does not apply to this contract.

18. Only the Singaporean company has the right to terminate the contract within 3 days.

After a day, the Singaporean company terminates the contract. Assume that Singaporean law does not have consumer law protection provisions and it validates contracts which grants rights to only one party.

Advise Joanna on whether she can challenge the ability of the Singaporean company to terminate the contract after one day.
