terrible service

<p>On 14/04/16 I phoned Cell C call centre to upgrade my contract I was told the upgrade will be for a straight up 100 top up on the 5/08/16 I received R50 airtime when I phoned. Into the call centre on monday I was told someone would phone me back I had to phone 2 times after that to find out what is happening and suddenly there was a diffrent stories. The ref I was given in April was 559123. Is this a way to treat a long time customer </p>
