Pump sticking already!

I've been using 3 of these pumps for less than 3 months, and 1 of the pumps is already sticking. You can press it down one time, and then it sticks. Now it's just me and my husband using these, so there's no excuse for this to be happening. We certainly don't abuse the dispenser in anyway. I seriously thought for the price, these would be more durable. The company should consider improving the dispenser quality or at the least, including several replacement pumps.
