Unauthorised upgrade of a contract

<p>Hello Peter</p> <p> </p> <p>My vodacom contract was **********ly upgraded without my consent. I was several times to sort this out with Vodacom since October 2016 but Vodacom seems not to care about my quiry. This has affected my credit rating because it reflects on my credit profile. The vodacom Social media department promised to contact me regarding this issue but they never did. The ref number of the logged querry is 1- ********** ********** and this quiry was logged towards end of March 2017. Apparently my Vodacom contract balance is R4336 Please assist.</p>
