Billed wrong amount

I have 2 contract with cells for the following mobile numbers and how much I'm being billed monthly. <br> Mobile *** contract paying R429.00 monthly <br> Mobile *** contact paying R199.00 monthly<br> Last month I deposited R429.00 and for some reason I was phoned numerous times but consultant who do not know the system and rude, Cell C must invest in taking their consultant to a customer service and telephone etiquette training. I explained to them that I paid and send the proof of payment. No one bothered to look for the proof and come back to me and advised that the payment has been received. But I received a text from Cell C informing me that the payment has been received but I still received this calls that I did not pay.<br> To my surprise last night they debited R868 and R203 for what I do not know. and what is irritating about phoning them I always get to talk to the consultant who are *********** and when I ask for the team leader or supervisor I get a message that he/she will phone me back and they never do.<br> I had a contract with MTN for 4 years I never experienced this level of incompetence money don't grow on trees, so I want my money back and if they continue lik
