MoneySaving Poll: Parcel delivery firms: who are the best and worst?

I have been very impressed with iPost Parcels recently (Or UKMail - they are fundamentally the same company). Pricing is very competitive. They give you a time window for when a parcel is being delivered, AND when they will arrive to collect. You can actually call UK Mail to track any problems if you need to albeit they prefer email so have to say it is an amazing service. HOWEVER... Their insurance is just a quick earner. We have only had a couple of problems with parcels, but any claim on their insurance is simply ignored. They will happily admit fault and promise repayment, BUT payment will never land despite continued promises of it being repaid to your bank account in a few days time. As such, when booking just skip the insurance bit since you would be better placed spending it on insurance sold separately to actually cover any loss or damage.
