Unable to connect to repository for Basic plan

I’ve bought the Basic plan for $144/year and wishing to be able to connect multiple APIs to repositories, but still can’t do it, the Postman showing message Upgrade your plan to link this API to a repository. Is this expected for Basic plan or is it a bug? Also in the case that such functionality doesn’t covered in Basic plan, can I have my money back? also how come no such description regarding this “Repository linkage” information in the Plan description?
