Buyer Not received item

[7ssscooter]

Help im new to selling on ebay, i have despatched an item with tracking, its been signed for, has the correct address on it but the customer is saying he hasnt received it. The package has been sent and the tracking is saying delivered. Unfortunately all parcelforce are signing their own machines due to covid. Am i liable to pay back the customer even though he may have item

if the tracking shows the item as delivered you don't have to refund the buyer

Is that definite because it was delivered today and now hes asking for a full refund if it doesnt turn up tomorrow, ive spent hours chasing it shouldnt they also be doing something as it feels like its just my problem

if you imput the tracking number into ebay and it shows the item as delivered ebay will close any not received case the buyer opens, and you won't have to refund
