I don't keep track of the bills to pay because they seem to come every few months without fail. All of them usually give me a few weeks to pay, except SKY (which is our Italian Satellite TV company) where I usually have only a few days. I received a letter last week from SKY telling me that I didn't pay my bill and that I needed to go to a ricevitoria SISAL (SISAL receiving office) to pay. I knew that I couldn't pay on the phone because they only accept Italian credit or bank cards. So, when I called SKY, they gave me three addresses of which the only one I knew for sure was the one I went to last year to pay for the SKY installation. The woman told me to pay both bills, the past one and the next one that I haven't yet received and is due at the end of the month.
