unacceptable

My account was in excess and it was handed over. I received an email on the 15 October 2014 asking me to make payment with a discount before the 31 October 2014 from Blake Collections. I made the payment on the 24 October 2014. I was liaising with Arlene Adonis from the bank and have emails where by she states that she has escalated the problem and that the account will be updated and closed. Then I receive a letter from the bank stating that the account is still in excess and that if I don't make payment legal action will be taken. Here I am trying to get my credit status in tact. I received an email from Prudence saying that I must still pay for fees accrued especially after I asked that the account be closed and have an email from Arlene stating I will not be liable for any payments. I expect an urgent response as I can not be liable for any further monies accrued.Note that all email correspondence I still have if needed.
