I wouldn't be happy with that either.... hardly did the job at all.

It is like with hairdressers, some have the knack and are naturally just good at their jobs, others just get by......keep trying, don't go back to that one, I sure wouldn't.
When my original one retired, it took me 4 groomers to find one which could actually cut well and knew more importantly how to style different breeds, she now does all our family dogs, you'd think they'd all know, but they don't

so just keep going, you will find one you like.......eventually.

You are quite right to be upset, I also agree in you stating your area, that way some of us may point you to one of ours, there are plenty of us on here who use groomers and even
are groomers.
