Thank you Standard Bank for bad service. Teach you

For the past 15 years I have a debit order on my credit card. Suddenly it disappeared and the arrogant lady that is harassing me is so stupid to tell me I made a manual payment in January which I did not do. Who is using my money without my consent whenever they want to? This is *****. For 15 years I had no problems and now suddenly the debit order disappeared and the arrogance to harass me 20 times a day with missed calls, tape recordings and calls of silence is unacceptable. Do you work properly.
