Narrative:
Cold, windy, and snowing at ZZZ, ground personnel did an unsatisfactory job of deicing the aircraft. At gate, deicing started at XA25Z and did not finish until XB15. Thus, snow started to accumulate on left wing which was first to be deiced. Told ground crew to apply more anti/deice to left wing. They did, but not to the last 10 ft of the wing. After push, deadheading pilot informed us that snow was still on last 10 ft of wing. Again, told ground crew who told us that they had already deiced it, and that it was fine (with an attitude). Captain insisted we could not go with freezing snow on the wing. We were informed to go to the deice pad. Then we were told that both deice trucks were broken. We obtained deicing through a contractor, who did an outstanding job. However, company inability to deice us in a timely manner resulted in an unnecessary 1 hour 47 min delay!
