After care service

I went in to return a faulty demister fan. The water bottle was leaking. The manager was called and he refused to come out and check the item. We basically only needed a water bottle - not a repair to a fan. Its been 3 weeks since the fan was taken in and no feedback received. I called twice and was promised a call back on the status of the repair. I need a fan now during this heat - not in winter.
