Returned one relatively low value item among a number of others totalling around 450 or so quid. Took 4 emails over 10 days to get acknowledgement of the signed for return, and another 3 or 4 days to get the cash back. Made a further coupe of orders, of which one included item was faulty. I can already feel the pain of arguing the toss and getting the money back. If it turns out like that then that's me done with NNs.
So, refund for the unwanted item received. No refund and no mention of the faulty item, value just £22. In the meantime, I'd ordered another 100 quid worth of stuff. Have sent an email, will see whst happens. No normal company would jeopardise a customer relationship like this, given the business. Very strange.
