Shocking, 'don't really care attitude, as long as you pay.

Waste of time. Full of promises and excuses when they don't arrive, or arrive severall hours later than agreed.. Technician couldn't fault finding, so I had to tell him what was wrong. Don't bring the right equipment to site so had to go and buy it, which took 3 days, then and charge for 3 callouts. (The parts replaced have been replaced by the same technician at least 3 times, each time with a new excuse). Disgustingly untidy workmanship.
