18th December ordered Sony headphones. 19th December payment taken on my debit card by PayPal. Same day supplied with Royal Mail tracking code and advised order would soon be trackable. 20 days later Royal Mail still do not recognise tracking number. Contacted seller who advised that Royal Mail had held up delivery but wouldnt say why. Subsequently advised Royal Mail had difficulty in identifying my address and was asked to confirm it which I did.I have lived here for 40 years and never has there been any delivery issue.Some days later again told that Royal Mail were holding up my delivery for unknown reason. Three times I have requested evidence that the parcel was handed over to Royal Mail.. Have never been supplied with this information. Three times have requested refund . These requests have been ignored. Only yesterday (6.1.21). they advised they would recall the parcel from Royal Mail and on return they would issue a refund.I am quite satisfied I will never receive my order or refund. Not surprising that I am sure in my mind this has all been a scam and fraudulent. Many others have described similar accounts. It is quite obvious Royal Mail have never seen my parcel and hence are unable to identify the supplied tracking code.
