Continuous Dismal Service-Standard Bank

To whom it may concern As at 19 December 2019 I transferred an amount of R1500 into my Credit Card which exceeded the monthly amount that was due as per YOUR Standard Bank mobile app. This week I received a phone call from Standard Bank informing that I have underpaid by an amount of approximately R1000. When I queried that the app stated otherwise I was informed that the amount reflecting on the app is not the correct figure. Despite the fact that I agreed to pay the apparent shortfall as per my conversation with the relevant person on the phone, I have decided to rather query this matter as such a discrepancy is based on the lack of service from Standard Bank. How can your mobile application stipulate the incorrect amount? For the greater part of last year I continuously experienced other issues with your Credit Card Department. If I am not mistaken the 23rd consultant was able to assist and rectify the matter and legal request after 3 months, which arose owing to Standard Bank’s widely known dismal service. Please can this matter be dealt with immediately.
