I ordered online a Gaming chair for my son on Black Friday, this chair had a big discount and was available in many other big stores in Greece for the same discounted price. Its status at the time of order was available and it was intended to be a gift for my son's birthday which is 10 days after Black Friday. After waiting for 1 month and following up many times the status of my order, I received an e-mail which simply said that my order was cancelled and that i got reimbursed the money I paid. I replied to the e-mail with a complaint but did not get a reply and called several time to complain, but the response was: "sorry that was a mistake but we cannot do anything about it". The price of that chair was 250EUR on discount, its current minimum market price is 400EUR. I was able to get it from any other online shop for 250EUR if i didn't buy it from MediaMarkt. My interpretation for what happened is that MediaMarkt creates fishy fake deals just to show that they have competitive market prices. I am sharing my experience in order to save other customers the bad experience i had with these unprofessional people.
