No Pick up bad attitude

We have an account with Xps and every time we request them to collect a parcel we tell them that we close at 3:00 (we actually close at 04:30pm) then the driver never come to collect the parcel when I phone your office the driver John says that he was here just after 3:00pm I mean if we close at 3:00pm then you should be here at 3pm but the best part is that John is lying because we where here every day till 04:30pm. I spoke to the branch manager James who promise every time he will monitor the account and bla bla,. This is now the 4th time in 2 months I am going to start looking for a other courier company that actually what our business.
