Goemans Appliances

Five years ago, I bought four high-end appliances from Goemans. I would not normally purchase extended warranty, however, the salesman told me that if the warranty was not used, I would receive $500 refund and on that understanding I purchased the warranty. Now my warranty has expired and after multiple phone calls to Goemans Burlington, I discover that I can have a $190 credit towards a new appliance costing more than $760 (x 4). Why would I need new appliances after only 4 years of use? This is usury at its best. Shame on Goemans for not providing full information and being totally inflexible. They won't even offer a service call.
