WHY IS IT SO DIFFICULT TO CLOSE YOU STORE ACCOUNT

I have been calling in since 13/05/2019 regarding closure of my GAME STORE ACCOUNT. On 12/05/2019 I settled my game account in store. In Promenade Mitchells Plain 7785. I have Called in everyday from 13/05/2019 , 14/05/2019, 15/05/2019 and on 16/05/2019 NO CLOSURE. NO CALL BACKS. This is unacceptable .Call Centre is another 30-60 minute wait for my query to be attended and when I get to the front of the Queue I am told I need to wait for the Closure department who has yet to CALL BAC**** I would like my account closed IMMEDIATELY and proof of confirmation sent ASAP. BAD SERVICE very disappointed in the quality of service I received.
