Very dissapointed and frustrated customer!

I am very dissapointed with Takealot Delivery options etc. Firstly, they dont deliver a "Washing Machine" on a Saturday....only in the week. How must the customer get home when busy working during the week. Not everyone is fortunate to work from Home. Secondly, the fact that an address cant be changed on their system is rediculous to me. They request customers to cancel an order( taking a risk for that product to become out of stock and/or missing out on the discount being given on that product. I will think twice of buying from Takealot again.
