Bad Customer Service

I had an arragement to pay my account on last month, but i failed to pay due to the fact that i could not afford to pay my account as i was not work during the riot, now my number have been deleted with no notification, even before i had to make arrangement because i recived an e-mail notification that if the account is not paid, i will be handed over. but now my number have been deleted, after 12 years of service.
