Terrible Terrible Customer service

The worse service provider to take a contract with, I settle my account last month on the 14th May. I called 06 June cos my credit score is showing missed payment and dropped my score, when I called Vodacom I was told it's showing as pre legal but they can see I'm not owing and don't know why it wasn't updated. Why is my the status and ITC not updated is appalling. I've never experienced such terrible service. I'm livid as this is affecting my buying limit. I need this fix urgently..
