Installation delay

I was convinced to purchase installation in strubensvalley store, now the is a week delay with this I threatened to cancel this the manager Kia basically told me to go ahead, this is after her stuff failed to explain the correct process to me the first time they called. She said all she can do is put me at the top of the list but cannot make any promises (she and her team need to go for further customer service training) Now I'm sitting at home with stove that cannot be used to cook. Who must spend money on takeaways till this is sorted. I need this installation to happen as in today not 25th February as the delay was not my fault please.
