Possible clients of the Kievoblgaz company, avoid it, and if you decide to deal with them, then take a month off and nerves of steel, at least. The most terrible cantora I've ever met. The staff simply does not know how to work with people. Untrained and irresponsible. They drop their phones and spend days searching for documents in their endless database.
Not a big backstory. I came to them at 8 so that they would transfer my documents to another office, which accepts them at 10. (no comments). As a result, installing the gas meter took about a month + sealing it, another 2 weeks.
So be prepared to pay faster than their work is done. Be ready to go to their office and sit for hours. And forget about the feedback at all...
