They tried to apply for the Custom Cash through the Citi app, which crashed on the first attempt, and were instantly denied on the second, possibly because they opened another Citi line recently.
Of the 267 reviews with a clear verdict, 68% are positive, 18% mixed and 14% negative. The praise mentioned most is great rewards. The most common complaint is poor support.
The praise reviewers mention most: great rewards (55 reviews), easy to use (52 reviews) and helpful support (5 reviews). For example: Runs three copies, one dedicated to gas and two to restaurants, and says it is nice to have 5% back in both everyday categories.
The complaints reviewers mention most: poor support (10 reviews), account frozen (2 reviews) and buggy app (1 review). For example: They stopped using the card because they were fed up with Citi customer support, and applied for a Wells Fargo 2% flat-rate card instead.
It's how well reviewed Citi Custom Cash is, out of 100. Negative and mixed reviews take points off, and so does having only a few reviews: a product needs plenty of them, compared with the most-reviewed products here, to reach the high 80s and 90s. It's worked out from reviews only, needs at least 5 of them, and updates as new ones come in.
