Extended Contract period

I had a 12 months contract with Mweb and this was supposed to run from Dec 2013 to Jan 2015. I recently tried to cancel this contract online but for some reasons this contract is ending in June 2015, very strange. So before i cancel i contacted Mweb to find out if there will be early cancellation fee as their system is saying that the contract ends in June. It has been about 2 weeks since i asked this but i am not given an answer instead different explanations f things i never asked, also was advised that i need to give in a months notice for cancellation but if my contract expired, why is there a need for notice in a period out side contractual period? I need to know if there will be any early cancellation fee and note that i do not see any notice necessary if you not explaining the need for notice.<br> <br>
