Almost non-existing customer service. There are a few windows for that and a few clerks but they…read moreare absolutely disinterested and trying to get rid of you as soon as possible without any real help or compensation. I bought there a wifi router last summer. Sadly, it was not compatible with my laptop, so, I could not use it at all. After few days of trial, I took my laptop and router and vent to Mediamarkt, where I bought it. Clerk could not fix it neither. So, I wanted to give that router back to the shop or exchange for something else I can actually use. When I asked about it , got an answer, that as I have opened the box with router it became second-hand product, and they do not exchange or take second-hand items back! From the bottom of my heart !!! what kind of answer and what kind of service is that? I lost my money, that router is still somewhere, and for now on I'll avoid Mediamarkt at any costs and will advice to do so for anyone I know...
