Uk Visa and Immigration Kings Court Chambers They lie to still my money. Internet

I needed i visa to go to London for 2 weeks so i was looking online and i found their website which says that they provide visas so i applied on their website. A week later they call me and said that they can help me to get a visa, and i would get it on the time that a requested and would get charge 450 pound which was a lot but i still agreed because i was told i was gonna get the visa in time. Then i receive a call which i explained why i needed a visa, and that was consider a consult for them. After that i was over charged and i requested a invoice so many time, i never received. I did provide them with the document they requested, which they never reviewed because they kept asking for the same thing for two weeks. I told them this is not proffessional and i want to cancel my case and get my money back, since its been almost a month and i dont have my visa. They replied to me that they don't provide visas, and only help me prepare to get a visa, which this is not what i was told. And doesn't make sense for me to pay that big of amount just for them to tell me what document i need to apply for a visa, which i already had them. After that i did read a review which i should have done it before that states the same thing, they will trick you that they will get you a visa and then will tell you that don't do that. Now they will not refund my money which to me that is called stilling. So please people don't trust them, if you need a visa they cannot help you on that.
