Bought an OEM EGR second hand off ebay, it turned up broken (part where plug clips in smashed to bits, cant have been in transit as it was very well wrapped up with loads of bubble wrap) sent it back on the 21st of this month and I do have proof of postage but when I enter the code into royal mails website it says 'an update can only be provided when an attempt has been made at delivering'
I've messaged the seller and they haven't replied, can I open a case? I've checked my purchase history and the part was delivered on the 8th of November so not quite a month yet.
