just putting this obvious scam here for anyone who gets one similar and has any doubts - had two like this during the last few days...names are always different so no point in highlighting those.

as I can see an amount of $ 64 which was charged to our Mastercard on the 12 May so
the amount you have refunded is incorrect. Please see the attached scan of purchase order!!!
