Bad service from Makro

I bought a Laptop a week ago with Windows 10 included, just to realize you need the product key to proceed and activate the software. Well the box had an Product key but not the complete key, there were a lot of numbers missing. I've tried, phoning, WhatsApp which operates like robot, and emails for assistance, with little results. Nobody seems to worry about the client. I will go there if I could, but I am 400kms away and must now be satisfied with remote assistance which doesn't exist. This is very sad indeed and a bad reflection for such a large business. 1 out of 5 for them, will think twice before I buy there again.
