Nemotown City Football Club recently won the English Premier League. This was the club's first league championship ever. In honour of this historic achievement Nemotown City Council planned a victory parade through the city centre, to take place on 10^th July, which would culminate in a special celebrity presentation of the Premier League trophy to the Nemotown City FC captain by the legendary former player, Fred Starkick.

Javed owns a flat on Nemotown High Street. He recently placed an online advertisement for "a room with an excellent view of Nemotown City FC's victory parade and celebrity presentation". Natasha, a life-long Nemotown City fan who lives in London, was very keen to view the parade and presentation. She saw Javed's advertisement and contacted him. In consequence, Natasha entered into a written contract with Javed for the exclusive use of his flat from 8:00am to 10:00pm on 10^th July. The price was £100. £40 was payable on 1^st June, and the balance was due on 10^th July. The contract made no mention of the victory parade or of the celebrity presentation.

Natasha also entered into a contract with "Cars-for-occasions Ltd" for a car to meet her at the station and take her to the flat in style. She paid the contract price of £100 as soon as she entered into this contract.

On the morning of 9^th July, it was announced that the victory parade and celebrity presentation had been cancelled owing to a terrorist threat. Natasha therefore decided not to travel to Nemotown. She has recently received a telephone call from Javed, who says that the flat was ready for her on 10^th July, and that she owes him £60. Natasha disputes this and wishes to recover the £40 that she paid to him on 1^st June. Javed has spent £200 decorating the flat in preparation for the parade, with Nemotown City's colours. Natasha also wishes to reclaim the £100 that she paid to "Cars-for occasions Ltd".

What advise should be given to  Natasha keeping in view the above scenario.
