Service consultant did not change my contract

<p>Vodacom, I was terribly disappointed when I found out that my contract was not migrated.. On having initially opened the contract in January I went back to the branch the same day and asked that the contract be migrated to a Flexi 200.... This is the third time I have had to process this change and was billed incorrectly as a result. It might be the last time I ever have a contract with Vodacom unless this can be resolved. I need to be reimbursed for the months that I had paid excess. </p>
