Little help here

Little help here
 

Hi there!!

This is part of a complaint letter, I'm not pretty sure if the grammar in bold is correct. Pleas any help?, suggestions?, advice??


I visited the store yesterday in order to solve this problem, but they say that they can’t change my laptop to a new one because this model is not in stock. I have to wait until new merchandise will be in stock.


Thanks a lot!!

Best regards

I'd say exchange my laptop for a new one
