They never responded, if they charge me for it I will raise hell!
This was the original email they sent yesterday September 4th, my charger was replaced August 13th and delivered August 18th:
Hi xxxxxx,
You recently contacted Surface Support regarding an issue with your Surface that required a replacement power supply to be sent to you. So that we can better understand the nature of the issue with your power supply, we would like to collect the non-working power supply from you.
Attached to this email is a FedEx shipping label. Please print the shipping label provided, pack your non-working power supply into the same box your replacement arrives in, affix the shipping label, then drop off at a nearest FedEx location.
If you have any questions or concerns, please reply to this email. Thanks for your cooperation.
Sincerely,
xxxxxxx
Service Order Specialist
