account not updated

I have placed an order on the 16/03/2015 for 6pc Stainless Steel Kitchen Utensil Set (Avon) however I called 3days leter to cancel the order but I was told the order was already despatched . I was told when the delivery comes I must send them back but their never come. So called homechoice to inform them and I was advised their have received the order and they will scan it back so my account can balance again but that hasn't been done even today and when I check my account it reflects the next payment to be on the 2015/04/30 but I never even received the good.
