I sent two separate parcels to the same address on the same day. However, only one of the parcels arrived and I want to make a compensation claim for the lost one with with the Royal Mail. I'm not sure if this will be a problem, but I just want to check, I threw away the certificate of postage for the parcel that DID arrive and I'm wondering if the post office will need to see this one as well as the one for the parcel that DIDN'T arrive (which I do have). Can anyone advise me on this? Thanks in advance.
Also, these parcels went abroad to the USA, will that affect my claim?
