It's more that I'm afraid that they will deny the refund request, and then I won't have anything else left to say. I was wondering what you guys though about my other option: explaining how the laptop is significantly underperforming and I can't accept a replacement (which really isn't far from the truth, the difference being me trying to persuade them there is something wrong with the laptop itself).

Why dont you call them from a different number and say you will be placing an order soon as a business customer but you are not certain whether or not the device you want is fit for the task and you want to know if it will be possible to return it if it turns out not to be.

This way you can have your cake and eat it and then make s decision from there.
