We finally convinced to owner of the ISP I work for to upgrade to an alcatel (nokia) 7750 SR12 and I need help desperately

I have tried contacting Nokia directly to set up a service contract, I have tried rep after rep, no one will call us back, and we've tried since OCTOBER. We NEED a current (19.10.R2 )release of the SR OS, or he's going to make us send it back. Contact me via DM if you need to, but I need help.
