First one occurred in Friday , where they should have come at 2 PM , but until 5 PM , they did n't showed up . I asked time to reschedule the maintenance problem on Sunday , as i had to go on Saturday and they agreed . I asked them to get as fast as possible and they said that they usually start dispatching technicians at 9 or 10 AM .

Based on the preceding passage, answer the following question What may be the reason I 'm calling and trying to set up a time ?
Because the crew never showed up for the initial call and I needed to get something done quickly .
