Asus All-in-one
8 weeks waiting for warranty repai

ASUS have my computer for just on 8 weeks and I cannot get information as to what is happening with it. When I ring I am told that the head of the service dept will ring me back and he does not!!
I ring again and they say they will send it to him again.
I ask what will happen if he again ignores it - I am told they will just do it again.
What??? forever???
I ask who is this persons superior and I am told he does not have one.
I am told if I am not satisfied I will need to put my complaint in writing.
What hope have I got??
