OVER CHARGED !!!

On the 29 March 2016, the amount of R246.79 was debited from account. My contract with Cell C is \supposed\" to be R199pm including BIS. When i phoned customer care the evening of the 29th March 2016, the consultant i dealt with had no idea what i was trying to say. He just said that i have BIS recurring.<br> The problem is...is that on the 28th or 29th February 2016 i upgrades my contract to a straight up 50 top up. My number was migrated where i lost all my benefits which i agreed to. In the evening i put R60 airtime so that i could use BIS.<br> The very next day, i phoned Abram from the retentions department and told him that i had changed my mind. (I never received the upgrade phone which was a Samsung J5). He then migrated my number back to my previous contract which is a straight up 100, I asked Abram whether there will be any extra charge for this and he clearly said no. I will still be paying my R199. (All calls are recorded, Cell C must listen to my call from Abram)<br> I have also sent Cell C a letter giving my 1 months notice since my contract expires on the 2nd May 2016.<br> Now i get the sms from my bank saying that the amount of R246.79 was debited from Cell C. I want this sorted out!"
