Poor service by supervisor

I had an account with edgars which was paid off in April 2019, after paying i contacted edcon with proof of payment and i was promised that my credit profile will be update accordingly, until today my profile is not updated, i have spoken to edcon telephonically requesting for update and they kept referring me to different people. i was then asked to send an Email to Sandile Mabaso 3 weeks ago and i did, until today he has no knowledge my email, when i call him he is always not available. you would expect bettr from a supervisor by Sandile has been *********** and i am not sure if its becouse of my skin colour or what that results in my matter not getting urgent attention.
