pathetic service by cell c

I had loaded R65 of airtime, I purchased a blackberry bundle. There after changed my tarrif plan. There had been no warning that bundles shall be removed. I immediately contacted cell c and notified them about the issue. They promised to get back to me within 24 - 48 hours. They had not resolved my issue thereafter. I followed up on the problem. I had spoken to a supervisor named shaun, he promised to resolve my issue in 20 minutes. He didn't. I contacted them again, and spoked to a guy named leon. He promised to resovle the issue. He did not. I spoke to a lady named minenshle. She had told me that they forgot to submit my report. Its been almost 3 days. And I've spent 3 hours in total in calls. And no one has seen to my issue.
