Never helped

I went to Vodacom about an account then was told to contact the TransUnion , on TransUnion account I am blacklisted as I try to explain to the people at TransUnion that I paid my Vodacom bill and it's all upto date , they say it's not and I must contact Vodacom for a letter stating that my account is up-to-date and they must clear name , TO THIS DAY I'm STILL WAITING for the email and help from Vodacom but I have nothing at all and now at the point of telling everyone never to use Vodacom at all
