I placed an order on Saturday night and made a mistake by ordering a 0mg instead of a 6mg. I emailed on Sunday morning to explain what had happened and to change my order accordingly. I heard nothing. I then received an email saying that my order had been dispatched and the item was still saying 0mg so I emailed again to ensure my order would be correct when it arrived. I received no reply. The order arrived this morning - 3 working days after it was placed but the item is the 0mg version. It is a shame that customer services obviously do not communicate very well with dispatch as, although the mistake was mine initially, I would have thought my order could have been rectified as there was less than 12 hours (over Saturday night time) between me placing the order and sending an email explaining my mistake. This is such a shame as the selection of flavours is large, the product seems good and the delivery time was correct to the minimum days quoted.
