I was wondering if anyone has found a way of getting customer support from Dell UK?

I purchased a very expensive laptop and have ordered an upgraded battery around a Month ago following weeks of trying to get answers as to where to order it. Only to receive a couple of messages saying the order was delayed so I called just over a week ago and finally got hold of someone to speak to who said my order status would be elevated to a higher priority and then nothing?  I tried calling today and after spending around half-hour being passed around the call centre cut off my call whilst I was in the call queue a couple of minutes ago so I am trying this route as a last resort to try and get someone to sort out my order for a new Dell Battery?  How on earth can it be so  difficult to get a hold of something as simple as a new battery?  I do not want to buy non-genuine parts from eBay so come on Dell sort yourselves out.  This business of putting the phone down on people in a call queue is really bad practice and very costly for customers as they have to pay new call charges all over again with the risk of it happening again.  As you may gather I am a little angry!!!!
