Shampoo dispenser is great. Not so much for conditioner

I bought this as a house warming present for a friend who saw the them at my house. It looks good and the shampoo side is working well but the conditioner has stopped pumping all together. Tried to re prime the pump but it isn't working. I'm starting to have the same problem with the conditioner pump in my shower but mine is over a year old. Disappointing...
