This data provider apparently employs only complete idiots as programmers.
We get data from them every week and there is always something wrong with it. This week, some of the rows were missing values in a text field.
Today we get an update where they claim to have fixed the problem. They may have filled in a few boxes but while doing so, they have gone through and deleted every occurrence of the '0' character in the data (so if something said "1002 South Street", it now says "12 South Street"). They also seem to have accidentally deleted a bunch of values from a different text field.
Seriously, even the government has better handling with the data they give away for free!
