Worst service ever

Why is it that my account has been paid in full but according to trans union only half of my account has been paid. This has been 3 months of struggling to sort this out after I paid in full. And the worst of it all is every source of communication that I've tried I just can't get through to vodacom.... Veryyyyyy bad service. I will tell everyone how bad they are and I swear if this does not get sorted I will go to social media and blow this up
