Unresolved account issue

<p>A vodacom consultant called me to ask me whether i would like to migrate to a higher plan at R40 difference to my current account. I agreed to it but received my account which was R220 difference. I called Customer care where Muzi assisted me and gave me a ref nr ********** 52. A few days later i received a sms saying the issue has been resolved and closed. This was not the case as i received another bill of the same amount??</p>
