I am a client of Miway insurance, the company is very ***********. I receive a message on the 04 January 2022, saying my premium didn't go through on the 31/12/2021 whereas my premium date its 20th of every month. I called and I was told that, that could be due to the other clients doing early or late payment arrangements. So where do I fit in there? Because I haven't made any arrangement of late payment. They are just ***********.
