Terrible service. I used them at Christmas as they still guaranteed delivery (this was 1 week before). I sent 8 parcels on the same day, some of these did not arrive until the new year. Don't bother contacting their "customer services" as they will not reply, they do not provide any other way to contact them except email. Also do not waste your time contacting UKMail directly as they just fob you off stating that they cannot respond to ipostparcel queries. I vowed never to use them again until last week (mid February) as I had an urgent parcel that needed to be delivered next day and our regular courier is 2 to 3 days. I dropped the parcel off at their dept Thursday morning to ensure Friday delivery. The parcel arrived Monday dispite paying for next day. Yet again no reply to any emails I send them. If anybody at ipostparcels bothers to read these reviews then please contact me to discuss what dreadful service you offer.
