Sorry Glad, as I said the last three signed-for items were not updated, even on the IOM system and after they were delivered! No word of a lie.
Does anyone know where the IOM Post Hub is in the UK? Does IOMP even know where it is? When you ask at IOMP no one is able to give you a straight answer.
I buy veggie seeds online and the producer/seller uses the RM 48hr service for the delivery. The last letter sized package I tracked (a small jiffy bag) was collected in Worcestershire and went directly to Preston the same day/evening . It then went down south to the Princess Royal Hub in north London(!) and sat there for two days, then back up north to Leeds for another 24 hours then over to Preston. The next I heard was when it was delivered three days later. It did appear on the IOMP website as being delivered but was shown on the RM tracking site as still being in Preston. So clearly the two systems don't 'talk' to each other.
RM letter post, as you have stated, is now a second class service unless you pay for the premium. I think what RM need to do is be upfront with its customers and redefine the timescales for their service levels and for IOMP to assume responsibility at the earliest opportunity.
