Poor procurement management

I did apply for Vendor Portal at Absa and it was last year. I was soon be able to login at their Codeplex from 2022 August until 2023 October, unfortunately when you login system say no Contract Loaded. I did make Follow up and to my surprise I always get email from Codeplex about any changes they made, I'm confused whether I'm at their database. This year I got email invitation for Absa Coupa and I was requested to answer Questionnaires and I did Complete them 24/02/2023 I also Upload certificate documents and later, they demanded insurance liability and also provide them. After few months I made follow up and I was told they need share certificate and I also provide. I have 14 months with codeplex and 8 months with Coupa, but both of them there's nothing to Display when you login I have try to Contact Absa Coupa support with email and they fail to assist clients and resolve matters come up with Solutions They have fail me I did not expect this kind of treatment from one of best and Big Bank. Every day I Contact Coupa support with emails and no respond Where exactly, we have to lodge complaint and assisted I think their still good Samaritans from Absa Procurement who are dedicated and hard workers. Please stop playing with people's emotions and Time.
