Taiwan Receipt Lottery

I just tried yesterday. I have three 200ntd winners from Mar/Apr. The 7-11 I always go to said they couldn’t use my APRC to redeem them “because of my name.” When I pointed out that my ID has my Chinese name as well, they still wanted to use one of the employee’s 身份證. I said nevermind, I’ll go to the bank. Why is this so hard?

Edit: I just now tried again. I spoke with the manager at the 7-11. She insisted that I couldn’t use my ARC, that they can only redeem with a Taiwan 身份證.

What do do? Is there anything in writing somewhere that I could use to educate the employees?
