Still waiting for my umbrella!!!

My husband & I bought a garden umbrella for Summer but never got to use because it was broken. We took it in for repairs at the Centurion branch where we purchased it and more than 2 months later we are still waiting! I must say that the customer service is quite disturbing. It's really not fair that as a customer you buy something, pay for it fully but never get to enjoy it. Summer is almost over and we never ever got to use our garden umbrella. I'm also upset by the thought of having to drive to the branch frequently to find out why there is a delay. This is unacceptable and totally unfair. I now just want a refund plz!
