Greedy and dishonest scammers.
During the first visit no investigation of the problem was performed, technician admitted himself no work was done and needed and yet took the full price.
Even though he claimed to be always available during the weekends, nobody picked up the phone, neither answered emails on the next day when issue reappeared. I had to spend all weekend without electricity.
During the second visit, after I insisited on investigation, the problem was identified and turned out it could have been easily found during the first visit if the technician would be more attentive. Again full price was taken. They have promised to do the report and nothing was done.
The owner was very pushy and aggressive on the phone. Very unpleasant experience. Don't recommend.
