Correção de texto "I paid the Housing Benefit overpayment"

Olá pessoal,

Gostaria que pudessem me ajudar com a revisao do seguinte texto:

''I paid the Housing Benefit overpayment on 02/05/2010.
I made payment although I have known that I never received the Housing Benefit.
I felt pressured because you said if I fail to make the payment my case could be referred to the Country Court enforcement action.

I have checked my bank statements and I had sure that you have not paid me Housing Benefits.
I would like you refund me the amount of £ xx xx That I paid.

If I do not receive any significant reply within 10 working days I will take this case to Court.

I am sending my bank statements and a receipt of the payment enclose this letter''


Desde ja obrigada!
