Can someone tell me how do I find report for cost breakdown for each item removed and shipped back to me?

Long story short some of my inventory aged and been removed automatically, and I have noticed that some small items under 100g measuring no more than 10cm 10cm 4cm for some reason are now classed as oversized and fulfilment fees with weight 80kg+ and I'm wondering amazon sneaky changed items weight and charging me 80 quid each to return an item in the envelope!?

I've only noticed two listings and they both same size and both 70 quid + to fulfil each has 1 unit available, but because I think its scheduled for automatic removal listing shows as out of stock so I cannot request dimensional and weight remeasurement. So they going to ship them and charge me 100s of pounds.... and how many they done already?!

So I need a report where I can see all items shipped to me and how much they have charged for the "service" can someone please help? Many many thanks
