Budget Insurance Refuses to cancel my policy

I informed my broker on 05 June 2025 that I would like to cancel my insurance with budget. She informed budget right away because I didn't want to have them deduct premiums at the end of June 2025. Budget deducts the money end of June and so is the new insurance company, so I have double deductions. I write to my broker again and she assures me she informed budget on time, budget calls me and refuse to cancel my policy saying they can only do so end of July. I have given these guys enough notice and i need them to cancel this policy because i am not going to pay them, my broker has proof that she informed them on time. i am feeling sick by how this company is behaving. the call center lady tells me Thell be covering me 50% with the other company, what nonsense is this, I'm shocked, i need these people to cancel the policy as instructed, they keep on asking me why do i want to leave and if they can re assess, I am not interested and they tell me it is standard procedure they cannot cancel the policy before i answer those questions. i told them i am not interested in whatever they are selling, and they are just refusing to cancel the policy. I did not even have to give them a notice as the law says, one can cancel insurance at any time as requested. please help me, I'm feeling sick.
