Lenovo — New pc

Address:

5 john wood houses upper largo KY8 6HB

I bought a new pc on september the 2nd however i was downloading windows updates and i ended up with a blue screen and i cannot do anything with my pc i contacted support and was sending email to and fro and in the end they said they cannot send me recover discs because they are saying my pc came without an operating system
it did it came with windows 10 home preinstalled and no matter how many times i told the operator she just kept saying it didn't come with an operating system
i keep telling her it diod but she would be as well as calling me a liar and then closed the case she was wanting me to send my pc in for repair but it would be a lot easier if she were just to send me the recover drive she was going to send one but someone in the back dept said my pc didn't come with an os BUT IT DID
HELP because i have a brand new £500 pc which i cannot use because of someone's stubborness to believe me
