Dysfunctional call centre that never answers!

I have tried to call Experian's call centre numerous times over the past few days and the call centre never gets answered. What's the point of having a call centre if you never take any calls? I have also sent emails which are neither acknowledged or responded to in any way. This is really disappointing, and concerning given that Experian is the source of all our credit information which are used to manage to make or break a consumer's credit reputation. Please answer the phones or provide additional contact information where your services can be accessed!
