My number removed and deleted without my knowledge

I have had problems paying my contract for the past 4 months,then eventually I did and made payments of R7200 but to my surprise when I tried and did a sim swip I was told my number has been deleted,apparently by the legal department But now am confused why was my number deleted even though I made payments,made payments in September but my number was deleted in October why And what does it mean coz I’ve been to a Vodacom shop and they can’t help coz the contract has been closed by the legal department
