MIWAY INSURANCE BAD BUSINESS PRACTICE

Completely unacceptable business practice from miway insurance, regarding my car insurance i have with them. How can you as company proceed to do a debit order on the 21st of Oct and i am only getting paid on the 25th. My deduction date is for the 26th of every month. When i called the agent and manager proceeded to say it might because i missed a payment which i did not. They also said they check to see if there is my money in my private account in order to deduct money 5 days before the agreed date.
