Shocking product quality and customer service

In mid January I purchased a wireless air keypad. After a month to six weeks it stopped working.

I returned the item to the store that I purchased it at. They sent it for repair. On return from repairs even though the item was less than 3 months old I was told I needed to pay for the repair as it was water damaged. Not having the time or energy to fight I paid the repair fee.

When I received the repaired item it had weatherproof on the box, so I am not sure why I am being charged for water damage, it seems disingenuous.

The final straw was that in addition to paying for a weatherproof item to be repaired, the item still does not work.

I called the Centurion helpdesk to try and troubleshoot getting the item to work with no luck. The consultant was rude and unhelpful. This company does not honor their guarantees and delivers the worst customer service. Beware!
