Misleading transactions when buying players

I was told by Sweetnitro we are only allowed to buy two players at a time.....when I opened up to screens on pc to buy two players I only received one?!
My complaint followed by a demand for refund has been ignored?! Surely as a loyal customer they would be interested to at the very least be fair to us????
you attempted to use an exploit to gain an advantage and feel they aren't being fair?
Their rules...
