Inexperienced staff

I was at Edgars Garden Route Mall to close my account yesterday. Now I received an email that information is outstanding and therefore my account could not be closed. The email states that you tried to call me and expect me now to call Edgars back to resolve the issue. This issue should've been resolved while I was in store. Please resolve this matter urgently due to me not willing to go back to the store or phone Edgars
