failure to resolve an error on Foschini's part

On the 2nd May 2015 I posted a report on HelloPeter. Foschini responded with an empty promise to resolve the matter. I've settled my account a few times and requested to have it closed. Foschini staff failed to follow through with my instructions, kept the account open and billing of magazine subscriptions (that I never received and actually cancelled) continued. This has affected my credit rating and also resulted in me being harassed by Foschini with messages that my account is in arrears. How does an account go from settled and closed to in arrears? Pathetic service from this organisation!
