Toshiba P50 Not received within 16 working days

After buying a Toshiba P50 laptop earlier this year from Incredible Connection, the screen stopped working without any reason. Being under warranty I took it in for repairs, after which the shop assistant told me I will have it back in 10-15 days. After 15 days I went in to Incredible Connection Woodlands, and after waiting more than 20 minutes for assistance, I were told that an assistant will phone me back. The assistant only phoned me back just before five on Saturday afternoon saying that the issue is being referred to head office. After being without a laptop for more than 3 weeks I am fed up with waiting, and not sure if head office will be able to be of more assistance!
