I have just had Premium Delivery options removed due to my On-Time Delivery Rate falling below 97%. How is this metric by Amazon even remotely fair when it is fully down to the courier? I send all orders on a next-day service and dispatch everything on time with valid tracking. What more can you do as a seller? Deliver the goods yourself!!

Seller support has no interest; they just say to solve the problem with the courier.

It is so harsh and unfair that I am penalised for something that is totally out of my control. I understand if the problems were because I had not dispatched on time or without tracking. But I do everything I can to meet the Amazon metrics. The only thing I am failing on is the only thing out of my control; how is that a fair system?

Also, what seems like a major scam is that if I joined SFP, then the On-Time Delivery Rate isn't even a metric that exists.
