Purchased a international delivery from UPS via Packlink. The delivery was supposed to take three days, so far it has been ten days. Reason for the delay given on UPS's website - commercial invoice missing. I completed the invoice, printed it and watched the Packlink employee at the Packlink drop off shop tape it securely to the package. So if it wasn't there it means UPS in transit removed it. Package contained some food for relatives in France so it's now all destroyed because of the delay. Have emailed UPS - no response. Telephoned them, they hung up. Telephoned again, they hung up. The package was sent with additional purchased insurance so I am covered. When I try to make a claim via UPS's website it says my (newly created account because of this incident) is not linked to my tracking number and I need to link it. To link it I need an account number, which UPS have not provided me with. So impossible to contact UPS via email or telephone and impossible to make a claim. I use many mail/parcel companies regularly and this has hands down been the worst one ever. UPS is not the cheapest so there really is no point in using them if their service is this atrocious.
