Verbose Tech LLP & OpusLabs Handyman - Ionic project

Hi,would like to know, if any freelancer or customer experienced in purchase code from VerboseTech LLP or OupsLabs

I already purchase and pay extra (all payment done) for their customization work…but unable to get any support and documentation.
With me already received apps source code and back-end admin (compiled code)…but no support or database details…quite difficult to operate…

Not sure any freelancers or expert out there can advise…

Thanks
