Jarrod Lo devised a web of lies for three years, tricking several victims many of whom he met through social media and dating apps into signing up for mobile line contracts. He took on the persona of a wealthy Korean, "Pak JH", who had inherited a large sum of money. He even dyed his hair to look the part. One of the victims is a university student (who cannot be named). Jarrod reassured the student that he would pay the bills and claimed that his twin brother would take over payment.

(a) A few months later, the student received a bill for $2,345 of overdue phone bills from ShowTel and Jarrod was uncountable. Explain three possible legal arguments that the student can rely on to challenge the validity of the contract between the student and ShowTel?
