Very poor service

We had all our windows replaced with a renovation back in 2014 and we have had issues that were never put right and we are still waiting to have then sorted. The installation was shocking and even their installation manager agreed as well as the sales man too but little was done to fix the issues. We have had two of the large windows develop manufacturing problems and have been waiting over 8 months to have them replaced they have now cancelled on us twice (two days off work waiting for them) and we are still waiting for a new installation date.(so 3 days lost work) It looks likely that this will be more like a year before our issue will be addressed. Their support people on the phone are doing their best but the overall system of after support is just not ok. In all honesty, I can not recommend them based on price and service as there are many other window companies that have just as good product and way better concern for their customers. Simply, I can not see any justification for anyone to use Everest. I do hope that this review will help someone avoid all the issues we have had and still are having with Everest.
