Afeedah has been instructed by Azliza to buy a computer

for a price not exceeding RM 6,000. Afeedah then had ordered a computer from Ariff Communication in her own name for a price of RM

6,500 since that was the lowest price in the market. When Ariff Communication delivered the computer,

Azliza accepted it even though the price exceeded the amount she had authorised.

When Ariff Communication demanded a payment, unfortunately Azliza refused to pay on the ground that the said price was too expensive and in fact it was bought by Afeedah herself.Discuss whether there is contract of agency between Afeedah and Azliza?
