Account suspended

Good day, I hope we can solve this problem. We made a mistake by paying this month money for Vodacom with the old reference code. The account was change from old Bussiness toe new Bussiness name. I was not aware that the account number was changef. We struggle from the 12th with Vodacom to transfer the money from the one to the other one. It is a Bussiness number. Last night they suspend the account and the guys need the phones as they work away. We' ve email POP numerous times, we went in to the branch and call numerous times. Is there anybody out there to help me solve this problem. P
