the customer service I received most recently when making a warranty claim against a faulty pair was slow. In addition, I had to buy a replacement pair then apply for the price difference between the faulty pair (which I bought in the sale) and replacement pair (now back to full price) from customer services. This I found totally unacceptable. With genuine warranty claims, a replacement pair should be sent out directly with no need for the customer to faff about paying upfront then applying for a refund.
