Please help me on my situation.

hi. i worked at saudi arabia. my work is housemaid. my contract was 2 years, i stayed there for 2 years and 5 months. they gave me a 2months vacation. but, they didn't pay my vacation, which it was written on the contract that they should pay my vacation . 2 days before my flight back to philippines, they arranged my papers, i don't know what paper that is, i thought that it's  a new contract, but then i didn't sign anything. on the day of my flight, they didn't give me papers. they just gave me my passport and they said that if i didn't come with in 2 months, i'll get block , they also brought me a roundtrip ticket. so, i'm at philippines already, since i didn't sign anything and i'm mad that they didn't give me my salary vacation and i don't have day-off, i decided not to come anymore. it was dec 2, 2017 when i get here in philippines. my flight back will be on jan. 26,2018. after new year, it was january 2, the employer of my dad from riyadh wants to get me. i said yes and i decided to give a try, besides my dad was there. yesterday, january 11, i received an email from my past employer . it was an scan document, its my renew contract. i don't have signature in there but he wrote my name and there is a verified stamp in there. he still doesn't know about my decision cause i don't have the guts to tell them. but now, it scares me. i don't know what to do . is there any possibility that i'll get block in Saudi even though i'm done with my 2 years contract and i didn't sign a new contact? and i don't have re-entry visa also i guess, i'm also sure that it's not a final exit cause they brought a round trip ticket.  what should i do? i really want to grab the opportunity at riyadh.
