Worst treatment ever

I worked at nutun for a year. A full year dialing TFG Ex legal second placement and from month one I was reaching my target and making commission monthly, in August or September I was shown my permanent contract and told I wasn't able to sign it due to your end financial what what and they gave me a 6 months contract promising me to sign the permanent as soon as the year end financial issues where done I signed it, then boom they chanced me to another dying book in October, in November they changed to another one and in December they changed me again then in January they put me on level up meanwhile every month I was changed books, another story came up that the company decided to part ways with TFG then they won't be able to take me permanent anymore because they don't have finances to cover my salary. This company did me dirty and treated me like an option when I showed my dedication everything and all these decisions they made knowing that I am pregnant and I need this job more than ever.
