When you hear the phrase "your call is important to us", it becomes clear that you will have to wait a long time. But Volgogradgorgaz came up with a way not to force the subscriber to wait. They invented a new ending of the phrase:
Your call is very important to us, but all the operators are busy, so call back later. And the operator is one, and the waiting time in line is zero. This is Gazprom’s know-how.
