Service Experts Home Services by Enercare

I purchased furnace and a/c many years ago from Service Experts. Have had the maintenance plan for over 10 years. Inexplicably, THEY cancelled me AND sent me a cancellation bill of 135.00. So I have called 4 times trying to get reinstated and find out what is happening. I drove over to their "office" to see a sign- no office here call a 1-800 number. So it appears the company might be in Kanata perhaps. I was told my issue was put on high alert however no one has called after a week. I no longer have any interest in service of any kind from them. Once it was sold to Enercare, no one carried filters or anything with them any more. They would tell you to buy your own- well something that basic can no longer be carried- seems like not much point in having this company any more. No service, no people to speak to, charging me for their cancellation? Well go ahead and cancel me- I was an excellent customer. However time to move on. Do not use them- they are not local. Find a local company to provide goods and services.
