RCS Card Complaint, Customer Service Department Worse Service in the Industry

I am RCS Card account holder and i use my RCS Card as my Transactional account, on the 24/6/2024 i have requested R1250 Cash Advance that was accredited to my account successfully, after that transaction i was left with positive balance of around R88, on the 25/6/2024 when i logged on my RCS App i realized the duplicate adjustment of the same amount R1250 by RCS Head Office and Mafikeng Branch. When i called in they said they will look into it and unfortunately time was moving without the feedback, i then logged the complaint on the 4/7/2024, i have never received any call from the complaint department, i then send a fromal letter complaint and on the response they said there's no duplicate, i was extremely unhappy because i know that someone is not doing what she is being paid for and did nothing to look at my query, so i then told my myself to wait for the posting of the statement which was yesterday, after i rceived the statement i have rep**** back to the last email from the complaint department with the attached statement showing 1 X R1250 deposit and 2 X - R1250 debits adjustments, and even after I have sent the proof, they still did not correct my account or apologies for the inconvenienced caused, i am extremely disappointment at the level of support and competency in RCS Customer care and Compliant department, I don't want any special treatment but to do their work and fix the mess they have caused.
