Cancellation on contract

My contracted ended on 4 June 2018. I was unaware of this as I never receive monthly statements via email or post. Nonetheless, my contract had continued yet at an increased price? Why is this? Why was I not contacted or advised of this?!? Whose to say I can afford this increased amount?!

I have sent through email requests since Monday to have your cancellation department assist in terminating my contract and I have had no response.

Please assist immediately! I am out of the country and am only available on email.
