Query: Not pleased at all.

While viewing several batteries, all Nikon EN-EL3e batter packs, somewhere Cables4u switched with the same battery number except ending with an "a" or Nikon EN-EL3a. I did not catch it and ordered it. When I sent them an email asking to exchange or for a refund, they answered "sorry we do not carry that item". I emailed again for a refund and they never have replied. So buyer beware, bad customer service and make sure you have the correct item. Very disappointed.
