Unwillingness to help

In 7 years of having our contract we have never defaulted in payment. This month the debit order bounced (even though there were sufficient funds available). Nobody bothered to contact to inform that they will be cutting us off. Yesterday the lines were cut off, and even though we have committed to making double payment at the end of the month, they still refuse to switch us back on until the end of the month. I am disgusted that this is the level of service a loyal customer receives.
