Court against the grandmother

So to start, here’s my background, I’ve been raising my babies on my own since my baby was born in April 2020, I had no help what so ever from their dads side of the family, it was always either they raise them alone without me or I raise them alone without their help there was never no co parenting, no reasoning.. but I raised them alone because their father was physically abusive, but my fingers, kicked me, threatens me and our older son at knife point, but his charges were dropped due to good behaviour.. then my lease was up so I asked if they could take ‘‘em til I found a place so I finally found a place 2 hours away from the town we lied in for two years (their dads hometown) they’ve decided to file for custody with no visitation rights for me and my babies.. mind you his sister threatens me at 12am while my babies were asleep and banging on my door and screaming, and their dads mother (the grandma) has mentioned on the court documents that she was unable to reach me to serve me and to get ahold of me was difficult, I have her number, and my kids auntys number and their home phone number and the grandma works in the same building as my mom and sister and brother and step dad and uncle.. but she was unable to reach me? She ignored all my messages over the past four months that’s she’s had my kids, her daughters even ignored my messages when I asked food my kids but they told the court I was unfit and moving around alot and not stable for my own babies.. I thought my babies would be okay with her til I found a place for me and my babies again, I just found out about this court application filled by her and my babies dad 2 days ago and I found out from an old support worker of mine who just happened to be at court when they told the judge I was hard to reach.. she told me and I attended the next court date and they rescheduled for 4weeks til I get legal assistance.. like is this possible for a grandmother and ex abusive father to take. Full custody with no visitation from me? I just moved in the new place 2 days ago as well and even had my kids name on the lease for when they could come back.. this is all bS and I hate that I have to fight this alone.. 🥺
