A struggle to cancel the contract !!

I got a contract 2 years ago and it’s coming to an end this month. It’s weird enough that I NEED to call to CANCEL the contract. But it’s more weird when I keep calling to cancel but none of that is being done. Why must it take long to cancel this contract? I’ve been calling waaaay ahead a month to cancel but ITS NOT HAPPENING. Can someone look into this and CANCEL THIS CONTRACT? I’m not getting any messages letting me know that I’ve cancelled.
