[急求]法国购物的premier tax free税单，回国后应该

请教各位大侠，前些天去欧洲，法国巴黎春天购物，退税公司是premier tax free的。以前去欧洲都是最后走的时候在机场退税取现金，但这次是罗马出境，因为提前知道现金退税的窗口暂时取消了，就在巴黎春天现金退税了，用信用卡做了担保，退税单在罗马出境时意大利海关已经给盖好章，但还没有寄出去。
现在的问题是：我从国内寄税单给premier tax free，是应该寄到哪个地址上，是退税时给的Tully business park, response paid, ballinahown, Co.Galway, Ireland的爱尔兰地址么？
官网上也没有找到可以问询的邮件地址。。。
官网FAQ里有写：The sales assistant in-store will provide you with a stamped pre-addressed Premier Tax Free envelope. You can send your Tax Free form for free in this prepaid envelope within the country of purchase, however, Tax Free forms posted from outside the country of purchase may require additional postage.
If you did not get a pre-paid envelope, please post your Tax Free form back to the country office of the country of purchase.
从这里面看还有一个可能是寄回法国？
求回复，谢谢！
