bad service

Last year I paid off my edgars account and send an email to have it closed, the feedback received from edcon confirmed that my account was closed and that should I need to use the account again I will need to re-apply. July 2018 I received an sms indicating that I have a credit available. I went to edgars at Carnival Mall to close the account again on the 15th of July 2018. The consultant phoned the call centre and I was assisted by Nombuyiselo Nkambule and she assured me that the account was permanently closed. August 2018 I received another sms saying I have credit available and to my suprise I find out from Vinolin Krishnalall that my account wasn't closed. I'm not happy with service from Nombuyiselo, clearly she didn't do what I had asked her to do and putting me at risk. What if someone else had re-opened the account and used it? Bad service. I will however like to give a big compliment to Vinolin Krishnalall for an amazing service and patience.
