Incredibly bad service! Touch screen of laptop defective. Sent on February 14 for repair.
February 26 received quote for the repair
February 27 quote signed return for repair
March 20, no message from media market yet, contacted customer service; parts are not available so laptop cannot be repaired (how's the quote then?) We are looking to send the laptop back to the media market branch and we receive a promise for compensation by March 24 at the latest.
Still called every day since March 24 .. so now March 29 still no laptop and no response
