Blocked by Vodacom because I had no credit score 3 years ago, this should go away after each year

You know what is absolutely stupid?? I have been with Vodacom for over 15 years. In 2019 I was enquiring about a contract phone and the person who assisted me put me through the system to check if I qualify. At the time I was unaware that I needed to have a credit score to qualify. Because I did not have a credit score I obviously did not qualify. Now 2022, 3 years later I have a credit score above average but I am still being penalized for the time they tried to qualify me. Now I am forced to take my business elsewhere. This is very sad and very stupid! I have never had an issue with Vodacom or its service and I don't want to change my service provider. Now I'm forced to do so.
