Hi everyone,

I’m a new seller on eBay and would really appreciate some advice from experienced sellers.

I recently sold a Botslab 4-channel dash cam system listed as “brand new (box opened).” The item was complete, unused, and in original condition at the time of sale.

After almost a month, the buyer has opened a return request under “doesn’t work or is defective,” mentioning WiFi connection issues.

My concerns:

• The buyer did not contact me before opening the return
• No clear evidence (video/photos) has been provided
• This type of dash cam requires full installation (adhesive mounts, multiple cameras, wiring), so I’m worried it has already been installed and used
• If adhesives are used or removed, and protective films taken off, the item can no longer be sold as new

As a new seller, I want to handle this properly and fairly.

My questions:

1. Should I accept the return straight away in this situation?
2. If the item comes back used (adhesives applied, scratches, missing stickers/accessories), can I deduct from the refund? If yes, how much is considered reasonable?
3. How do sellers protect themselves from buyers who install and use items, then return them as “faulty”?
4. Is it normal for buyers to open a return without messaging first?

I want to follow eBay policies correctly but also avoid losing money unfairly.

Any advice would be greatly appreciated. Thank you!
