Amazon price matching eBay Issue

Hello,

For 2 weeks we have had our buy box suppressed by Amazon, our RRP has been £11 for 2 years no issues ever. Now Suddenly buy box suppressed no communication from Amazon, they have now said they are price matching eBay at £20.99 a crazy price increase… they are also not the cheapest price online. Amazon are not helping and we are losing literally thousands now… as are Amazon also… it’s just so odd, we are a vendor.
