I'm not sure I can help, but I think you may be confusing Dial a Rod with DynoRod that I have heard of and which has been around for many years. I tried looking up DialaRod and it seems they were only recently incorporated less than a year ago on December 2010 with a share capital of £2. Their company office is registered in Dartford. I am not suggesting that this is a problem, but it would explains why there is not much history or information about the company anywhere to help decide who would the best to go with.
