how homechoice make their money

I ordered a kitchen combo in march, I haven't receive it n I'm being billed from march. When I call the head office I'm told its being dispatched from their head office so they cant cancel. I asked them to stop the debit but they tell me the cant. the the lady I spoke to Inter said she doesn't know where the parcel is located and refused to give me the managers contacts and refused to give me her surmane. I need to cancel this please gug ***
