Account Closed with no contact

I logged a query on the RCS website almost a month ago to be contacted as I wanted to close my account. No one made any contact with me. I then received a sms last Friday with my available credit. Today I go to the store to purchase something and I'm told my account is closed and I need to reapply. Please tell me when I was contacted to close this account and who confirmed this with me. Im am extremely unsatisfied with the service received and I would like someone with authority to call me.
