Makro Online beware

I purchased an Item online on the 15th September. I noticed that I made an error and tried to cancel the transaction, they don't have an option to cancel online and require that you should phone them. I phoned them the next day a Monday and was told it was cancelled and that I will be repaid within 7 to 10 days. The following day I received notification that the item is out for delivery. I phoned again and was told not to accept the item. It has been 3 weeks and no repayment. It appears that they don't know there are from their elbow.
