Poor service levels, inability to track parcels and unable to provide most services offered on its website

They are the most unreliable, lackadaisical courier I have ever used and they are in no way interested in improving their actual service levels, or event keeping the promises they make in their advertising. I had a parcel collected from another address on an account on 3 days ago and then scanned the shipment incorrectly so they cant tell me what the correct waybill number is, where is the parcel or when its going to be delivered. I just have to hope? Its taken two working days for them to even recognise and attend to the issue after being forced to argue with multiple people that the details given on tracking were incorrect. They dont care about the service they offer customers and their call centre agents don't seem to understand what customer service actually means. They enjoy turning around and trying to blame poor service customer's actions/inactions but they dont communicate effectively to guide customer's through their processes and they cant acknowledge when they are in the wrong or not living up to the promises they make. Their website markets and advertises all these services, some of which are no longer even available (like overnight services) and all of which are incredibly unreliable. I've been let down over and over by this company and I doubt Im the only one
