Car Warranty - claims department does not answer my calls

I'm so disappointed in the customer service for claiming on a car warranty, I've been trying to get hold of the claim department for two days with no answer, but sales department is very fast to respond. I'm hoping I will get assistance as I've been with the cover for almost 4 years with no claim but today since its claim time, I get no answer. This clearly shows DialDirect is not reliable, and I regret being a loyal customer for all these years.
