Its really quite essential and urgent that buyers are shown the correct dates for their postage choices  and handling times -  otherwise for me as a seller as well as ebay as a whole becomes a place that delivers late and this is really ruinining the trust relationship we've all worked so hard to build up. I am certain I have lost return customers due to this

I'm sorry to be grumpy but I have been very patient waiting for a fix, and appreciate its not your fault but the fact that this hasn't been seen as urgent or essential is really quite worrying. 

Please do feed this back accurate dates Its one of the basic things the platform should be able to provide especially when metrics are so tight on on time delivery.
