Relocated from FL to CA; now being laid off

I recently relocated from FL to CA for a position with a company in San Francisco. They paid all relocation expenses and the offer said if I separate with them or they ask to me leave for any reason, I will have to pay back on a pro-rata basis as stipulated in letter; less than 1 year 100% after 1 year 50%. I agreed to take the position and move to CA. Now 6 months has elapsed since I accepted the position and relocated, but company just sent an email that I am part of the targeted volunteer to resign. The email said they will pay a severence, but you cannot collect unemployment since they will inform unemployment that you voluntarily resigned. A bit strange this analysis. Also you will need to sign a release form before collecting that severance pay. Any relief options that I have or leverage to negotiate with them as, I do not wish to pay back since this termination as the email said is not for cause more of convenience. I know for sure they will let me go, but do I have an option to request that they pay my relocations cost back to FL since I moved here only for the sole purpose of working for them, but 6 months later this is option is being pulled off. I know my contract is employee at will per default standard. Thank you in advance for all your inputs.
