Sonic French Brush with Dotting Tools (Size 10, Size 12, Size 14, Size 16)

I ordered 5 sonic French (Germany) brushes and was given 5 777F Kolinksy (England) brushes, which are cheaper & generally not as great as sonic brand. Company apologized for sending wrong brushes & informed me items were not in their inventory. If you did not have the right product, why did you sell me something cheaper & not available. Be alert for False advertisement
