Query: lousy and slow service

I paid extra for Air Next Day service. Item was advertised as available and ready to ship immediately. Item eventually arrived two weeks later. I had left for a trip. Item was eventually sent back to merchant. Merchant didn't credit me for item returned. I had to email merchant and wait for another 2 weeks before item was credited. I won't buy from Willoughby's again.
