Paid up letter headache

I wouldn't advise anyone to get a contract with cell c... I had a contract with them which expired in 2021 last year i found out whilst doing a credit profile that i owed them when i enquired i was told i owed 5 rand after back and forth of trying to understand what is was for with most not being able to tell me with one saying it was for postal which was strange considering i wasn't getting statements via post i eventually paid it and on 23rd of December it was loaded and I was told it would take 48 hours until today i haven't received that paid up letter i couldn't get a house for my kids because I am bad payer over 5 rand that no one can explain and they said there are no turn around times when I called i can only wait imagine
