Dear support, I bought 25 credits today and wanted to remove the password from meizu pro 7-h, as a result, I spent more than half and still did not remove the password, Is it possible to return loans or something else to come up with?
I attach logs

Flashing, erase frp, erase userdata supported
for Exynos platform, go to \FLASH:FASTBOOT
for Qualcomm platform, go to \FLASH:QUALCOMM
for MediaTek platform, go to \FLASH:MEDIATEK
- Flashing requires bootloader authorization by server
- Unlock bootloader supported for some Qualcomm and Exynos devices via \FASTBOOT:SpecialTask
- Any Bootloader authorization will consume credit, use it with caution at your own risk !!!
- To avoid any toubles, please always use official firmware !!!
- Flashing requires server authentication and UFI CREDIT, goto \ACCOUNT for the list of services and costs
  !!! WARNING !!!
- Authorization should only be used for normal flashing with official firmware that match to your model
- Special Tasks are bonus feature, if it fails you can not claim a refund
  Reset Flyme Account Lock was released for old models, it will not work for new model.
  Any Special Tasks in MediaTek platform require write access and will not work for this model due to secure boot.
- Service cost for [Meizu] M1792:
  MEIZU_FL(Bootloader Authorization(QC, MTK, EXYNOS) - Including Identify, Flashing, SpecialTask): 5 credits
  MEIZU_UBL(Unlock Bootloader(QC, EXYNOS [Private testing phase])): 10 credits
  Do not rename the phone model directory !
  Every Special Tasks will needs to use Bootloader Authorization, you pay for authorization not the specific task !!!
  You have to select the CORRECT firmware that match your phone model before Identify !!!
