It's all in the SMALL PRINT !!!!

I suppose I took the cheapest (ish) policy out for a flat I was renting. I unfortunately only stayed for 6 months and the policy was for 12. On cancelling I was told that I had to pay a penalty for early cancellation. The usual stuff. However what I couldn't believe was that it amounted to twice the amount I had left to pay on my policy! How I asked? Because it's in the terms and conditions I was told. I then said “oh well just leave it then and I'll pay it off as I was originally at 4.50 a month”. “No” I was told you’ve informed us that you’ve moved out.
You know I get the penalty stuff but what I think is appalling is that not only are they no longer having to insure my home they want to charge me more than I had left to pay to cancel the insurance. I truly do not understand what the hell I am paying for. What am I getting? I suppose it’s a typical money spinning exercise? Exhausted tel conversation. IT’S ALL IN THE SMALL PRINT. Argh
