Laundry loses my sheets

Try another laundry service or wash them yourself?

Do your own laundry, either buy a washing machine or put them in the machines at the launderette yourself.

I used to go to the one next to my local pub, stick the wash on, have a beer, use the drier, have another beer or a coke if I was driving, and then it's done.

Sorry if it's not much help, but laundry services like a lot of things are subject to human error, and them losing the odd item is just part of life.

When I was 16 I got a summer job in a steam laundry in West Norwood. These were common up to the 1970s. The laundry came in big bags, and I unloaded them into a huge drum. Each bag had a ticket tied to it saying who the customer was. They had a contract with West End hotels. You had to count the items in and out. Sometimes things got stuck in the drum and ended up in a different bag at the end. You would not believe what filthy pigs stay in expensive hotels. Or maybe you would. Underpants and sheets with skid marks. Or other marks.
