CALL SERVICE SUSPENDED AFTER PAYMENT

My account is paid via debit order and because February had fewer days they decided to let my debit order go through at the 27th of February without letting me know. As a result there was no money in my account, as I only receive my salary at the END of each month, which was 28 February. I then paid my account on 03/03/2015, using the account info and Reference number I have. On 06/03/2015 I received a sms to pay my account
