Who do I call to mow really long grass?

Milwaukee WI

Description

Our regular service won't cut the yard b/c it's too long because they didn't receive the contract I sent back in the beginning of May, so they never cut it. I assumed they were following the 'no mow may' deal. Anyway, now our grass is WAY too long and I have no idea of who to call. I'd appreciate any suggestions! Thank you!
