Zero Customer Experience, Useless Customer Expertise

I've never ever in my life met a company who with staff that don't take the time to read a complain however is quick to respond without acknowledge of the actual complaint.

So here goes nothing, hopefully I'll get a literate individual to read and hopefully will understand this.

I had a contract with Vodacom from 2019 to 2021. Due to being misinformed by the useless agents I changed my payment method to cash. Due to some financial constraints, I missed a few payments however made all the payments at once. I even was called to upgrade my contract once it was ending. Now I decided to get a new contract and was told I got a judgement against my name. I asked for the balance, and they said it shows Zero on the system. How the hell can I go into judgement for a ZERO balance. I did send in a previous Hello Peter complaint and was sent a debt collectors number to contact. Why must I who paid my account in full call with my expense a debt collector when it's Vodacoms job to call me and rectify the mistake. If this doesn't get resolved asap I'm am definitely following the legal route.
