Only image and promises but nothing behind - Sales Co-Worker IKEA Employee Review

I am currently working for Ikea. I am not going into all the details, but I am pregnant, Ikea never sorted my documents for maternity leave so I had to contact HMRC for help. I took all my holiday before my maternity leave as that is a procedure in the company, and just before Christmas Ikea didn't pay my holiday and I am with £200 for the holidays, with no money to pay rent, and no money to buy everything necessary for my coming newborn child. The worst part is when I called the company they promise me to call me back as they are busy and no one ever does, or no one ever replies to my emails, so again I have to look for legal support to survive the month.
