Incorrect Billing & Benefits

<p>I have done an upgrade in March this year and the new upgrade was supposed to kick in May 2017 , when I checked my balance on the the upgrade date nothing was loaded. At the ed of the month I was billed at my old contract amount. June 1 2017 I was loaded with the same old contract benefits. When I contacted Cell C on the 2 June 2017 regarding this, I was put from department to departments and still nobody could give me an answer. I called again last Friday (9th June 2017)to follow up and was told someone would call me in 48 hours , today is the 15th June 2017 and nobody called me, once again I called them and was told that I have to wait for someone to call me. Does it take 1 week to sort out the contract? Is this the kind of service we get from Cell C? I am really disappointed with this service. I would like someone to contact me ASAP on this.</p>
