I've used them twice and found them excellent,but they won't be up to your standard.Do the same as you do with Auto electricians,get them to try their best and if it's not good enough don't pay them.
What is your problem? Go climb back under your rock. Perhaps you like wasting money paying for jobs that dont get done.
I have found I get some good advice from people on here who read my post properly and answer in a polite way. But you are just something else, I find your vocabulary some what limited.
Have a good day sir.
