We started using Business Post as they were called then earlier this year, the first deliver was never received by the customer, which we took as first time dealings, so after arguments and legal threats (by them not us) Business Post agreed to give us a credit note for the outstanding amount despite us asking for a cheque so we can take our business elsewhere.

They picked up 4 packages without us using a special book that they never sent to us that required the driver to fill out with delivery details. Then on the 5th occassion they realised there was a missing delivery book, so they stalled our delivery for over one week losing us another client.
When we lost or rag with them they pushed blame back to us on no dlivery book and insisted we close the account with them and a cheque for the outstanding amount.

They then proceeded to charge us 4 times the rate for the 4 deliveries due to no delivery book and said they would send back a cheque for a small sum of money which did not equate to what business we had done.
The National Manager Rob Earthy is by far the worst customer service manager in the country, I ask him to stand up online and defend his actions if these is any untruth in this review because he ignored my emails when I asked for details on the same.

You can check other sites doing online review sites and you will find similar negative reports about their poor quality service.
