Hollard not communicating

Last month my debit order was returned from Hollard insurance on the 10th of September for double the contribution amount,but I then left it as is. (Note my policy started on the 1st of September.)(after that the contribution was collected)<br> On the 12th of October I receive another sms from the bank stating that the debit order was returned once again but for double the amount when I phoned them only to tell me that they are taking a payment for October and November, which I don't know how they can debit it for 2 months straight without even notifying me in any way.<br> <br> Point being is that everyone has a budget and cant expect a debit order to be double the amount that is suppose to be.<br> <br> I am really not happy with the communication and the call centre just says that they can see that the mesg did not go through and also left it at that.<br> <br> really disgusted is is only my second month.<br>
