Still getting bad service!!!!!

I am still experiencing shocking customer service from Game. I was told by Mohammed on the phone that the problem I am experiencing is because I use my computer for business and it is not a 'business' computer even after explaining to him that the only programmed we use at work is excel!! I was told to bring the laptop in AGAIN!!! I refused and told them to collect, that was over a week ago still no replacement! I will now be taking this matter further!
