Breach of Contract and Bad Service

I open a Motor Service Plan Policy in 2012 at MFC and now they say that it has expired in December 2014 with out notification and I haven't even reach my millage as per the contract. Contract opening millage starts at 150 000km to 180 000km over 3 servicers- 1) 150 000km 2) 165 000km 3) 180 000km --- 30 000km contract distance - service plan duration 84months -effective starting date 23/08/2012 - no closing date. After making numerous calls to them not once have they rep**** with any info. I took my car in for service on Tuesday 23/06/2015 with the millage on 174 930km and MFC IS REFUSING TO PAY THE SERVICE. I am still awaiting for any response from them as I have phoned them again this morning. Had I known how ********* they are I never would have open any contracts with them. The other two contracts has expired as well without any claims. Warning don't trust them with contracts. Now I have pay for the service out of my own pocket.
