Cell C does not want me to pay them but keeps me in a credit unworthy position

I took up a contract with Cell C in 2017 and defaulted because of some financial troubles because of unemployment. The default ended up in a bad credit profile. I have since recovered and have reached out to Cell C to check how much I owe so that I can settle the account, but I was told that the account is sitting with their legal section. I tried reaching out to legal and somebody referred me to a law firm with does their collections. The law firm indicated to me that the account has been closed from their side or that the account has been retracted from them. I them contacted Cell C again, but I could not be given clear answers. I demanded to speak to a Manager and was given a team leader who promised me that I would get a settlement balance letter so that I can be able to pay and settle the account.

I have been calling Cell C for the past two weeks and I have not found success. It was difficult enough to owe Cell C - I don't understand why it should be difficult to have to pay them now. The team leader I spoke to has disappeared and has not responded to a single email I sent him. I cant find help from all the other team leaders that I find and I am also drawing blanks from the so-called legal department.

I do not know what I must be able to do to get the settlement balance letter so that I can pay Cell C and clear my name - maybe somebody needs to be bribed in order for me to get a service because I am now generating interest and other charges or penalties, when I could have settled this a longtime ago.

I am very angry at Cell C as I feel held to ransom and prevented from implementing my debt clearance and credit recovery plan!!!
