Vodacom suspends pay as you go number

PLEASE HELP My pay as you go Vodacom number suspended every 24 hours. I've been back in South Africa since 13 December. And have been to The Vodacom shop in Lifestyle on Kloof, Orbit Cellular on the 16, 19, 23, and 27 December for assistance. My number ***5xx has been on Pay as you Go since June 2019. Before that I was on contract for more than 20 years. My past account is settled in full and has or was never in arrears. The account however states archived and therefore every two days I am fully admin locked. Which means I cannot use my number at all. THIS CANNOT CONTINUE. WHAT MUST I DO TO BE ABLE TO USE MY NUMBER AS WELL AS THE AIRTIME AND DATA THAT I HAVE LOADED?????
