Line suspended

I thought i was being clever by paying my account manually, because i knew that by the 31 of december i would not have money in my bank account . So on the 28 december i did the payment that reflected the following day. To my suprise on the 19 january my line was suspended,prior to that no comunation was done. I was never notified of that. Now i have been calling and all the consulatant could say is \i do not know". I do not explanation as to why my line is suspended i need for them to fux their mess. And knowing very well that their techinical department does not work on weekend"
