Bad cancellation process

Hi, I have been to you store twice to cancel or close this account along with the credit protection plan. I have settled this account in July. yet I have still been receiving invoices showing me that the account is opened and they have been charging me for a policy that should of been cancelled already.

Kindly please close this account as per my settlement date and any refunds to be refunded.

The last invoice received shows a credit balance of 308.

Closing an account should not be this difficult.
