As the title indicates, I recently discovered this issue after communicating with a new contact station, BG5EBE. The callsign of BG5EBE has been reassigned from an old callsign, and I have not yet been able to contact the previous holder of the BG5EBE callsign. After trying several methods, including registering on QRZ China by changing "B" to "฿", I am still unable to find a good solution to the problem with my QRZ.COM account. Since I haven't found any relevant channels for reporting this issue in the customer service center, I have reported the problem to QRZ.COM via mail. However, due to the long delivery time and USPS's unreliability (or perhaps just bad luck), it is unlikely that this will be resolved quickly. I hope that anyone with similar experience or who can contact QRZ administrators can share their experiences and possible solutions. This would help my new contact station, and I would like to thank them in advance. I welcome discussion.
