DISGUSTING HOW CELL C WORKS WITH ******!!

I opened an contract with Jabba that is one of Cell C's 3rd party dealers and when my contract expired in 2017. I found out that they are still loading my number with airtime and also keeps adding it to my account. My debit orders stopped going off and I assumed that the contract came to an end, turns out that Jabba/Cell C has handed me over to an attorney and is charging me for loading unwanted airtime on my account and on an expired contract I might add. This is reflecting bad on my credit report and thus I am unable to apply for anything ells. I am highly disappointed in Cell C for having a *****ed and ********** company represent them. My repayment on that contract is now double the amount what it was since the debit orders stopped which by the way is not my problem if you load my account with airtime on a contract that has expired months ago. Please rectify this problem immediately.
