Terrible service

Budget insurance has been debating me on the incorrect date for a couple of months yet when I took this insurance I gave then a specific date to debit. I called last month the call centre and notified them of what is happening. The lady said she updated the debit order date and I will not have the problem again. But I see Budget Insurance once again debits me on the wrong day. Why ask clients when they want to get debited and do the opposite thing
