Здравствуйте! I am guessing that this might be an acronym for some kind of position/job, but I cannot find it. This guy who is talking has mailed a package to a company but they cannot find it. It was sent through Russian Post with a tracking number. He is describing his phone conversation with the guy at the company who can't find the package, (from context I guess he means on the website): "УКОМ пришла. Он говорит, "я не могу пробить ее. Зайдите еще раз на почту." На почту зашел, пробивать все нормально." My guess is that some kind of manager showed up to help? And said that he could not find the package? He told the customer to go to the post office again. The customer went, and said that he found it, no problem. (We find out later in the conversation that the package is, in fact, at its destination city post office, but has not yet been delivered.). Спасибо большое!
