Unexplained invoicing

Hi,can I please have a detailed explanation of how this account is in arrears. As I checked the invoices I was charged however no data was used and services were suspended within 3months of no payment. According to my understanding this is a month to month service and nowhere upon my signing up for this service was I told that I needed to inform rain if I was not going to continue for a certain period. I would like to reconnect my services again but im not willing to pay for something I did not use,it's daylight *******. This is my second follow-up from my first query, I await your urgent response. Thank you.
