Sunita wanted to purchase a new iPhone and found the best deal online. But before she gave her credit card details she decided to ring the contact number of the product provider to get more details and some advice as to the best version to buy for her needs. The salesman persuaded her to buy the most expensive model even though he suspected she probably didn't need it based on what she had told him. He indicated to Sunita the cost of the iPhone would be about $1,200 but when Sunita saw her credit card receipt later, she had been billed "$1,500". When Sunita realised she might have paid too much for her new iPhone she telephoned the provider to inquire why her receipt said $1,500 when she understood the price was $1,200. She was directed to the manager who said he would make inquiries and 'get back to her'. But he did not get back to her. Was this a valid contract? Give your reasons why or why not. What would be a suitable remedy in this situation? Your answer must refer to the relevant case law. (N.B. You are not required to use Consumer Law in your answer) ( Answer according to IRACC model )
