Dishonest OUTSURANCE

My yearly car insurance payment was due on 2nd May 2020. Outsurance company stated that the May insurance portion will be discounted by 15%. On 28th April I called them to inquire how it will be done for my impending debit. I was told by Nicole that it will be adjusted the day before the debit order. On 2nd May they debited my account with full amount with no discount for May. I phoned to Outsurance on 5th May at 8:00 and spoke to Clinton, who asked to give him an hour and he will call me back. Nothing happened so I called again at 13:50 and spoke to Bridget. She informed me that all managers are in meeting. I sent a feedback to Outsurance, but got a sweet talk reply, with no action. On 8th May I phoned at 8:48 and spoke to Veruchka. She said I will receive a call from the manager. I received call at 15:42 from someone, but the line was dropped. I believe the caller was Kyle. I called again at 15:44 and spoke to Neo. She went to look for Kyle, but she could not find him. My quick calculation is showing me that if they have some 2 million clients and they delay the refund by one week they will make themselves some R 350 000.00. On top of it I feel sorry for the front line employees, who are the lightning conductor for customers frustration, while the managers are nicely isolated and share the proceeds. This is done during COVID-19 Lockdown, which makes it disgusting.
