各位大佬，7 月底giffgaff之前退款没通过，就没在管了，看到论坛大佬不少退款成功了，今天去看好像没有入口了（论坛帖子中的入口都跳到了这个网址：Home | giffgaff Help），现在还有渠道退款吗？有话术吗？谢谢！或者有类似的比较完整的帖子吗？ 
我找到的话术如下： 
Dear giffgaff Agent,I have recently transferred my mobile number from giffgaff to another provider using a PAC code.As my account is now deactivated, I would like to request a refund for the remaining credit balance on my giffgaff account. Please let me know...
