Yours Clothing - Wrong billing address so cancel order please

When ordering I input my postcode and a scrolling list of addresses was shown but it would not accept the last item on the list when I chose it instead it scrolled to the address above it on the list. This input the incorrect billing address on the order. Therefore I contacted yourselves by email and was asked for the confirmation email which I haven't yet received. Also you requested my country name. Again I found that list scrolled to any other country but would not let me choose United Kingdom. You advised me to cancel the order. This is a request to do that. I placed 2 separate order.The 2nd one for navy crops £19.99 is ok. Please cancel order for black combat crops £26.99 please.
