Took all my money

Ive arrange with teljoy for extension on my acc. They sent me a email stateing that i can pay 50% of my total acc. And that they will stop the current debit order. Today they took both my current amount and the 50% discounted amount. Ive tried calling and sending emails but no response. I dont have any money left now so how im i going to get food for me and my jkids. They dont cate at all. Ive got the proof that they have sent me and now they took all my money out of my acc. The last ive got. Cause they didnt do as they have said. What am i going to do now. Where am i going to get money. My husband passed away in jan and i am the only breadwinner and because of the lockdown i didnt get any orders in. They took the last of my money with no explanation. Where am i going to get money now for food. Anybody please help!
