No account closure

I have 4x RCS cards from 4 different stores. No problem good service until you try to close the accounts. I requested settlement letters and instructed account closure instructions, paid the full settlement amounts within 5 days. It is now 30 days later , not one account has been closed and nobody can tell me why. You just hit a brick wall with no service. I e-mailed them , no response. With service on this level I will hardly recommend the company.
