No Acknowledgement of payment

I have settled my account with Direct Axis, through Norman Bisset and associates, and now I have been calling Direct Axis to send the paid up letter and all the time I get a refusal. Norman Bisset and associates says they have instructed Direct Axis that the account is paid-up. <br> This is really wrong as when they required their payment they were calling me everyday <br> <br> Can someone please help a customer out...
