Vodacom serious failure.

I have operated a Vodacom number since 2002. I have regularly upgraded until November 2022 when my contract expired and have used the phone on a prepaid basis ever since. I made arrears payments in three instalments. I use the phone on a daily basis for correspondence, banking, searches and numerous other functuons. On 01.01.24 My number - *** was blocked for no reason. Having repeatedly contacted customer care and the Vodacom shop at Cape Gate and numerous enquiries by consultant Kyle, my number could not be found on their system which is profoundly ridiculous. It seems to have disappeared - after 22 years. Kyle could not recover it and says he cannot replace the sim card and do a sim swap. I am extremely upset as that number has an enormous ammount of information and contacts and I challenge Vodacom to immediately rectify the problem. My other number is *** and email ***
