I’ve been made a fool

I’ve purchased pots November 2024 paid required deposit. Then. On the 18th December I got a message that my pots were delivered I called pres les to tell them I did not receive any pots. They said it’s not their responsibility for the pots left the wear house. I should call courier company. I did they said the post were sent back to Pres les wearhouse. My request is one. I want to cancel the contract and get my deposit back and leave this madness. I’m someone who suffering from a severe depression I can’t afford what Pres lee is doing to me. Can someone anybody please help me
