Hi Guys A customer bought an item from my online website, that I don't have instock, when I go and try to get this from my supplier I've been told a price increase and a part number change. I have gone back to my customer and told them about this and advised them if they still want the item they will need to pay extra or I can issue a refund. The customer is demanding I ship the item at the price they paid for it and are quoting consumer rights etc etc. My understanding on this, is I have the right to refuse and refund any order that I want; as nothing has been physically given to the client yet. Can anyone confirm this for me?
