Pathetic customer service and flawed system

1. I have two policies that you failed to debit me for one and failed to notify me until I called to update my banking details even though my account was active and open at the time with sufficient funds. 2. You still proceeded to debit me against the incorrect account after calling and confirming that the debit will be updated effective from this month 3. It is not my fault that you failed to debit me as per our agreement and suddenly I am liable to make a double payment as a result of your errors
