Billing Accounts

<p>I had 2 contracts with Cell C for 143.10 on each line, on 24 March 2016 i paid 143.10x2 via internet for both my lines and one line the contract was ending In May 2016 so after paying in march i was left with only 2 months to pay. On the second line i was left with 5 Months to pay as the contract is supposed to end in August 2016. I made another payment of R1200 on 29 March 2016 and i called Cell c to request them to split the R1200 into both lines. So on the one i was left with 2 Months they were supposed to take R286.2 and pay the balance into the 2nd line wich was supposed to be R913.8. So beacuse i was left with 5 months on the 2nd line that means they were supposed to take R715.5 from the R913.8 and refund me an amount of R198.3 because according to my understaing i shouldn't owe them anything after paying the R1200. Now i call today to check the status of one active contract line and they tell me that i have a credit amount of R98 and i have to pay R45 odds to make my monthly premius for June... My question is what happend to my other money i paid from the R1200?????? I want this resolved!!! I want answers, i need someone to give a me clear explanation to all this because i'm not willing to pay anymore cent from pocket!!!</p>
