Poor Service

I have a service plan that missed 1 payment. I called in as I checked my policy and it showed inactive. I called in and an agent told me that my policy was cancelled on the 20th of November. I asked him why did no one call me . He told me straight, that they don't do that. As a service provider , you contact your clients to assist them in need. Clearly not the case here and told me straight I am losing my premiums paid for the previous months. I asked to speak to a more senior person and I was told the person is busy and would call me back and it is an hour later no call yet. Totally unhappy with the poor level of service.
