once you have complaint and hassle from insurance just write to them and say you will only deal with them in writing from now on , better to have prof of what you said and what they sad to you , and you can respond to then with out getting all wound up.
i had trouble with budget insurance about a car i sold and the policy carried on they said owed £215 but sold it .. alot of trouble untill provided profe i sold the vehicle, writing all the way better...
but £50 for canceling a policy you have paid in full bollock get them reported them to the right peolpe ......something smells fishy to me....
good luck dont stop untill its sorted, and dont give in most people do , just pay what they say they owww its easy for most people just to make it go away..
