Oral - B Pro 3900 Stopped Working in 20 Days and Media Markt Refused Replacement
I purchased the Oral-B Pro 3900 rechargeable toothbrush from the Media Markt store on December 7, 2024. Less than 20 day...s after the purchase, the product suddenly stopped working while I was brushing my teeth. I initially thought the battery was dead, so I charged it, but it still does not function.
