Use to be with Norwich Union - now Aviva as my insurance provider. When bought Golf, they gave me some ridiculous price which I didn't wanted to pay so cancelled my insurance with them back in June 09. Ofcourse I paid cancellation charges, and on top of that they reimbursed £17 back into my bank account stating thats what they owe me. Also it shows in my bank statement for month of june as a proof

Anyways, now after 7 months, I've received letter from them stating I owe them £199.18

WTF
Rang them to talk about and collection department said I need to pay this and there is no way out. Obvioulsy I said f*** that, I'm not paying anything. Ask him to transfer my call to customer services as he didn't have any answer to reimbursement I received from them. Customer service didn't give me any accurate reason either and bloke said he will give me ring after finding more info on it. 2 days have passed, heard nothing from them.
What do you guys suggest, what should I do
