If only we could rely on their honesty. A BIG international company (that we thought we could trust) tried to do some work for us and within a short period we realised they did not know what they were doing. We fired them, but still ended up paying a large amount for their time spent. We wrote it off as school fees. Even resumes do not help. (We did check those). Now we have to set up contracts to protect ourselves, which in itself is wasting a lot of time. Our project was postponed for 3 months. Maybe somebody out there can learn from this and take precautions.
