Standard Bank has a very poor service

Standard Bank VAF So last month, October 15th, Standard Bank VAF did not debit from my account, as they always do. They harassed me with text messages that I missed an instalment so I eventually made a manual transfer to their account. On the 14th they reminded me via sms that my monthly car instalment is due on the 17th of November, which is today. Since the message was vague, not telling me whether they would be debiting or I should pay, I went ahead and wrote them an email, reminding them to debit. When they did not reply I went on ahead and transferred the instalment to their Standard Bank VAF account, and sent proof of payment to Siphosethu Soyama, the consultant who assisted me with the October instalment. As soon I did all that, a debit order went through. Can Standard Bank please assist me getting that money back hence we never agreed to two instalments in a single month.
