Berlin All-Inclusive Welcome Card with Museum Island

Wide range of places to visit free public transportation.

I am writing to express my extreme dissatisfaction with my recent ticket purchase. My issue is very simple: Where are my QR codes? The tickets provided by your system clearly lacks the required QR code, rendering it invalid. Upon arriving at the service center at Berlin Airport, I was informed that the ticket provided by your system is invalid because it is missing the QR code. This caused significant delays to my schedule, and I had no choice but to purchase another ticket, which is completely unacceptable. Despite contacting customer service multiple times, all I received was confirmation that my payment was successful. However, this does nothing to address the real issue. If your company cannot provide a valid ticket, why is payment even being accepted? This is highly irresponsible and has caused major inconvenience and financial loss. I demand an immediate explanation for why my ticket lacked a QR code. I also request a full refund and compensation for the inconvenience and additional costs I incurred.
