The tiler has repaired it using a pen filler. And it still looks pretty bad. Should this tile be replaced or is this a normal repair method and result?
The chip being filled is 1.5 inches long
No, you should not have chipped tiles after a new installation.
Just ask your contractor to replace the damaged tile.
Correct I agree
ask the contractor to replace the chip tile
Sometimes small cracks can be filled but in this case I would have replaced the tile. Ask your contractor - he or she will likely be happy to accommodate you.
No it is not normal. The tile should be replaced.
