Over charged on monthly premium

On 02/12/2015 I contacted the call center to find out why I was over charged on my monthly premium.<br> <br> I was told by the call center representative that he would look into it and contact me back first thing in the morning as the accounts department had already closed.<br> <br> Up to date 21/12/2015 I have received no feed back. This is not the first time this has happened!<br> Really disgusted at the service!
