Paying for nothing

Good day I spent the whole morning struggling with your call desk regarding my account that was not recharged and to get throught to someone who can actually assist me in cancelling my contract. In the end, I had to draw the conclusion that my data bundle and airtime is then apart from my phone's actual contract seen as there was a difference in the latest debit order than the past 2 years' debit orders. Is this possible? I don't know, because none of your staff can actually tell me what is going on. As for the man who assisted me with contract cancellations - he literaly left me hanging on the phone whilest I could hear them having a fat jol in the back. All I want to do is figure out why my account was not recharged and cancel my contract that expires in June anyway. This is unacceptable from a network service that claims to be the leading network in the country. I refuse to pay for something so horrific.
