I want to port back to another network

Very ridiculous, they don’t want me to port back my number to another network, This bank needs to exposed and close down as their service is not good at all…. It need to be SHUT DOWN. I have been requesting to port back my number to Vodacom as Capitec Connect does not have e-Sim but they are not sending me back the code for approval. This their network is not even user friendly… They really need to be sued because I am now not receiving calls and missing important calls. Capitec needs to release my number back to proper cellular network. This is my number and I have been using it even before Capitec Connect was Created… Could you please give me back my number or I am going to sue the hell out of you.
